RKWard 0.6.1 - Support for R 3.0.0, new features for plugin developers

02 April 2013

A new version of RKWard is available download. The most important bit for most users will be that RKWard 0.6.1 works with the upcoming R 3.0.0, while the previous version will not work with this version of R. Users installing RKWard from source should note that you will have to compile RKWard after upgrading to R 3.0.0 or later. If in doubt, feel free to ask for help.

Besides compatibility, the new release brings new features and fixes. A particular development focus has been the addition of new options for plugin developers. For a more detailed description of the new features,see these mails, or refer to the usual documentation on writing plugins for RKWard.

The changes in detail:

  • New features and improvements
    • Add plugin for subsetting data.frames by rows or columns
    • On the Windows platform, add an new (experimental) binary startup wrapper (rkward.exe)
    • Added support for loaded namespaces that are not attached to a loaded package
    • Pluginmaps can specify their "priority". Pluginmaps with low priority will not be added automatically, when found.
    • Pluginmaps can <require> other pluginmaps based on their id (for cross-package inclusion)
    • Added new element <dependency_check> for dynamic version checks within a plugin (R and RKWard versions, only, so far)
    • Add guard against accidental usage of the standard distributed pluginmaps in a later version of RKWard (installed in parallel)
    • Easier (de-)activation of RKWard plugin maps using checkboxes (Settings->Configure RKWard->Plugins)
    • Broken or quirky .pluginmap files are reported to the user, completely broken maps are disabled, automatically
    • Implement basic dependency handling for plugins / pluginmaps
    • Added support for the upcoming R 3.0.0
    • Added <switch> logic element to switch between several target properties (or fixed values) based on the value of a condition property
    • Sort plugin gains option to sort data.frames by more than one column at a time, and options for type conversion
    • Add in-application debug message viewer (targetted at (plugin) developers)
    • Add setting to customize initial working directory
    • Windows only: Add UI-checkbox for R's "internet2"-option
    • New functions getString(), getList() and getBoolean() for fetching data in plugin scripts
    • Boolean properties now return a numeric, not labelled representation of their value, by default. <checkbox>es should be unaffected.
    • Added <optionset> GUI element for entering a set of options for an arbitrary number of items
    • Reduce CPU usage of plugins while idle
    • In the data.frame editor, columns containing invalid values are now highlighted in red
    • Added <matrix> GUI element for entering matrix or vector data in plugins
    • Improve key handling while editing factor levels in a data.frame
    • Added utiltity function rk.flush.output()
    • rk.set.output.html.file() gains argument to allow addition of custom content to the html header
  • Fixes
    • Add option to force-close a graphics window
    • Revert to building R packages form source on Mac OS X by default (controllable via compile-time option)
    • Fixed: lattice plots would not be added to the plot history, correctly, for some versions of lattice
    • Fix crash when trying to print, and neither okular, nor kpdf are available
    • Fix conversion from Numeric to Factor in the data editor
    • Fixed: If none of the previous plugin maps could be found on startup, re-add the default
    • RKWard is now categorized as Science/Math/Numerical Analysis in its .desktop file
    • Fixed: Yet another fix for hard-to-read function argument hints
    • Fixed: Device history was not working with more recent versions of ggplot2
    • Fixed: Option to include suggested packages in install was mis-labelled "install dependencies"

RKWard 0.6.0 is available - also on the Mac

24 October 2012

Today, a new version of RKWard is available for download. RKWard 0.6.0 adds initial support for debugging R code (a debugger console, and a display of current evaluation frames). Dialogs for - among others - t-tests and Wilcoxon-tests have been improved, a table of contents was added to the output window, and, as usual, many more features were added, and bugs were fixed, both in RKWard itself, and external plugins. Perhaps more importantly than all this, however, 0.6.0 is the first official release of RKWard to be readily available on Mac OS X.

Also, at this occasion, I'd like to take a short moment to look back: RKWard is approaching it's tenth anniversary, version 0.1.0 was released on November 19, 2002. During those ten years, at times, the project has been on ice, or going at glacial speed. But the project is still here and - driven by a wonderful community - it's looking younger than ever, after all this time. Many thanks to everybody involved!

As usual, please don't hesitate to send us your feedback.

    • Most plot plugins gain options to control margins and tick label orientation
    • Added option for installing packages from source (implicitly enabled on Unixoid platforms)
    • Omit comments on missing function calls in dialog code windows (e.g., if prepare() is unused, there's no "## Prepare" in the output either)
    • Output markup is now more XHTML compliant and easier to parse
    • Also save cursor position, folding, etc. for scripts. Note: Implementation details may be subject to change.
    • New function rk.list.labels() to retrieve column labels in a data.frame
    • rk.get.label() will now return an empty string ("") instead of NULL, in case no label is assigned
    • Do not offer to restore individual removed columns of a data.frame opened for editing
    • combined all Wilcoxon/Mann-Whitney-tests in one plugin (from previously two separate plugins)
    • Added polyserial/polychoric correlations to correlation matrix plugin
    • Added more compression options to the "Save objects as R code" plugin
    • Added MacPorts support, see README.MacPorts and bundle build script in the macports folder
    • Added dynamically generated table-of-contents menu to output document
    • Allow some markup inside <text> elements in plugins, and auto-add breaks only for duplicate newlines.
    • Reorganized t-test plugin, and add support for single sample t-tests
    • Box plot plugin gains more options for adding means

RKWard 0.5.5 - Enhanced robustness and many small improvements

19 March 2011

On the surface, RKWard 0.5.5, released today (download) may appear to bring only few changes. Internally, however, the GUI and the R engine have been split into two separate processes. This brings better robustness, and better compatibility of RKWard esp. with R packages based on rJava and RGtk2. In addition, many bugs and quirks have been fixed in various areas. And, in case you experience a crash despite of these improvements, RKWard 0.5.5 will attempt to create an emergency save file of your data in the last moment.

Please give this new version of RKWard a try, and don't forget: We are always eager to hear your feedback!

The changes in detail:

  • New features and improvements

- Re-organize the default toolbar actions of the main window - Detached windows are now restored in detached state when restoring the workplace layout - Workplace layout is now saved in a separate file, instead of in a hidden object inside the .RData file - Added R functions rk.save.workplace() and rk.restore.workplace() to save / restore a set of document windows - RKWard now tries to detect, when a workspace has been moved to a new directory, and adjust the paths restored script editor windows, accordingly - All pages in the package installation dialog now support sorting and keyboard search - Allow entering factor labels instead of only numbers, when editing factors in the data editor - Display logical values as "TRUE" and "FALSE" in data editor, and accept "T"/"TRUE"/"F"/"FALSE" in addition to "0"/"1" while editing - Add support for R functions loadhistory(), savehistory(), history(), and timestamp () - Moved automated testing framework moved to a dedicated R package "rkwardtests", and added documentation - Support pasting to the middle of the current command line in the R Console - Better handling of script-editor commands while the R Console is busy - GUI frontend and R backend now run in separate processes - Re-write of large portions of the R embedding code - Attempt to save workspace on crashes - Removed the remainder of the PHP scripting backend

  • Bugfixes

- Fixed: Crash when several environments on the search path have the same name - Fixed: Potential crashes when changing length of a data.frame that is currently opened for editing from R code - Fixed: Converting from factor to string in the data editor set values to numeric, internally - Fixed: On Windows, a wrong locale for LC_NUMERIC would be applied, resulting in malfunction of pdf() and postscript() - Fixed: Did not use system configured background color in data editor - Fixed: New columns would be always be added to the right, instead of to the left, in the data editor - Fixed: Would crash when trying to edit 0 row data.frame - Fixed: Output generated by external processes (system()) was not shown on the console - Fixed: Converting a variable to factor in the editor would drop existing levels, silently, and lead to NAs - Fixed: Cursor would keep jumping to the end, when typing a filename in the filename selection field in plugins - Fixed: Submit button would not become enabled in "Basic Statistics" plugin - Fixed: Portions of multi-line commands entered on the R Console would be run twice under some circumstances - Fixed: Lockups or crashes when using packages RGtk2 or rJava on the X11 platform - Fixed: R task callback handlers were not called - Do not load .RData file from current directory by default (configurable) - Correct interleaving of multi-line commands and the corresponding output in the R Console - Fixed: Did not respect system settings for tooltip background color in some styles - Fixed: Installation would continue, seemingly successfully, even if R support libraries could not be installed - Fixed: Function argument hints would sometimes persist after closing a script window - Fixed: Would fail to analyse structure of ReferenceClass-objects - Fixed: "Vector" mode in "Paste special" action did not work correctly - Also try to relay SIGABRT and SIGILL to the proper signal handlers - Fixed: Would crash on tcl/tk events in some cases

RKWard 0.5.4 - Plot history, bug fixes, and new possibilities for plugin writers

04 October 2010 - User:Tfry

The most visible change in RKWard 0.5.4 (download) may be the addition of a plot history for the on-screen graphics device. Supporting both regular and trellis plots, this can facilitate the creation and management of plots, considerably. Further, the data.frame editor now supports row names, and plugin authors now have new possibilities for scripting plugins, which we hope to put to good use in the coming releases. Documentation has been added for the functions in the rkward R package. Beyond that, there has been the usual bug fixing, and a number of assorted small new feature additions.

The changes in detail:

  • New features and improvements

- Added full-featured plot history for the onscreen graphics device - Added option to specify default onscreen graphics dimensions - Added option to disable function argument hinting - New functions rk.show.message() and rk.show.question() for user interaction from R code - New options for scripting GUI logic in plugins - The current object of an active data editor can be referenced in plugins - Allow sorting of results in help search window - The save-object selector in plugins now allows to save as part of a data.frame / list - Support row names in the data.frame-editor - Added option to autosave script files (enabled by default) - The tabbar in the main window now shows a context menu with options to close/detach a window - The tabs in the main window can now be re-ordered by dragging with the mouse (left click if compiled with Qt 4.5 or above, middle click for earlier versions) - Added alternating row backgrounds in data.frame-editor

  • Fixes and corrections

- Fixed: Running user commands would crash with R 2.12.0 - Fixed: Potential crash when editing data-frame with duplicate column names - Fixed: Graphics windows used to assume a minimum size of 640*480 pixels, even if a smaller size was specified - Fixed: Placement of several menu items was broken - again - with KDE 4.4 and above - Fixed: CPU usage would go to 100% for no good reason under certain circumstances - Fixed: On some systems, dev.off() would spawn two new graphics windows - Fixed: When starting with an empty table, RKWard would sometimes claim that this object has been removed - Fixed: Would crash when trying to configure toolbars under certain circumstances (workaround for bug in kdelibs) - Fixed: Crash while analysing some objects returned by XML::xmlParseTree() for invalid XML - Fixed: Error while installing packages with R 2.11.0, when archiving packages in a non-existing directory

Maintenance releases 0.4.9a and 0.5.0b

April 20 2008 - User:Tfry

Both the KDE 3 and KDE 4 versions of RKWard have been updated today. Most importantly RKWard now compiles with R 2.7.0 (which is due to be release, officially, soon). Both releases are available from the download page.

For the KDE 3 version (RKWard 0.4.9a), the only changes are:

  • Support from compilation with R 2.7
  • New plugin: Hodrick-Prescott Filter
  • Fixed some lockups during startup

The KDE 4 version (RKWard 0.5.0b) has the following changes:

  • Support compilation with R 2.7
  • New plugin: Hodrick-Prescott Filter
  • Fix a problem with plugin help pages not loading correctly
  • Better resize handling in progress and R input (readline()) dialogs
  • Somewhat better handling of the R event loop (esp. when calling "require(not_yet_installed_package)")

As usual, your feedback is welcome on our mailing list.

Bugfix release 0.5.0a (for KDE4)

January 23 2008 - User:Tfry

A simple but important bug in RKWard 0.5.0 was discovered a bit too late (in most plugins no objects were selectable at all). This is corrected in version 0.5.0a, which is available for download, now. Please use this version instead of RKWard 0.5.0. Other than the correction there are virtually no changes since 0.5.0.

RKWard 0.5.0 for KDE4 is released

January 21 2008 - User:Tfry

The first version of RKWard for KDE4 is available for download, now. The list of actual enhancements (see below) is relatively small, but internally a lot of code has been rewritten. The move to KDE4 / Qt4 provides a new foundation for RKWard, and offers a number of promising opportunities for further development, which we hope to put to good use, soon. The list of current changes over 0.4.9 (as far we kept track of them):

Bugfixes and internals:

  • make sure that R only handles SIGSEV, when the R thread is active. Should give better backtraces and less hangs
  • port to KDE 4

UI enhancements and new features:

  • object viewer was redesigned to use space better, and only fetch the print-representation when needed
  • add support for a focus-follows-mouse activation behavior of the MDI windows (Settings->General)
  • ability to mark arbitrary "blocks" in script editor and run them with a shortcut
  • more icons added
  • data.frame editor can be set to read-only mode
  • code completion in script editor shows icons for the different object types
  • settings dialog is now shown in "page tree" mode

Please note that this release has seen considerable code changes. This should fix a lot of small bugs not listed above, but also, of course, we expect there are a number of new bugs that we did not discover during testing. If you find some, or would like to share your opinions on RKWard, please contact us on the mailing list.

NOTES: Versions of RKWard 0.5.0 or higher are designed for KDE 4, and cannot be used with KDE 3. For KDE 3 use the 0.4.x versions. The build system was changed to CMake. Read INSTALL (also provided in the source .tar.gz) for details on how to build RKWard. Due to clashes with kate default shortcuts, the shortcuts for Run->Run Line, Run Selection, and Run All were changed to Shift+F7, Shift+F8, Shift+F9, respectively.

The tabs in the main workplace view no longer have a close button that is shown when hovering the mouse over the respective icon. Rather, there is a single button to close the current tab, shown at the right of the tab bar


RKWard 0.4.9 is released

January 14 2008 - User:Tfry

Version 0.4.9 of RKWard is now available for download. The following changes are contained in the new release:

  • Enhancements:
    • Improved user interface for CSV import plugin
    • Support drawing grids in histogram and stripchart plots
    • New plugin: Levene test
    • New plugin: Jarque-Bera test (by Germán Márquez Mejía)
    • Use the KDE default fixed spacing font for command log and object viewer
  • Bugfixes:
    • Fixed: Crosstabs plugin produces better output
    • Fixed: use.value.labels option was wrong in SPSS import plugin
    • Fixed: SPSS tables would only be imported to the workspace, when the edit option was checked
    • Fixed: correct installation of rkward.desktop file

In case you are wondering why the list of changes is shorter than usual: This release is one of the last releases of RKWard for KDE 3. Meanwhile we've been working hard to produce a version which will run natively in the newly released KDE 4. This will be released as RKWard 0.5.0 in - according to plan - roughly one week. We will continue to support KDE 3 versions of RKWard for some time to come, and probably also provide some new or improved plugins, but the main development will focus on KDE 4 versions of RKWard from now on.

Remember: Your feedback is always welcome on the mailing list.

Bugfix release 0.4.8a

November 11 2007 - User:Tfry

While development continues on the next versions of RKWard (including a port to the upcoming KDE 4), we would like to address some bugs that were discovered since the release of RKWard 0.4.8. This release (download) does not add new user features, but fixes several problems. The changes in detail:

  • Bugfixes:
    • More reliable C stack limit detection on some systems
    • Fixed: Console accepted pasted input while a command is running
    • Fixed: Analysis->Moments->Moment plugin did not use the order-parameter
    • Fixed: Crash on simple assignments in globalenv() with R < 2.4.0
    • Fixed: Meta information (labels) did not get shown correctly in the data editor
    • Fixed: Pressing the add button in a varslot with no object selected could crash RKWard
  • Internal changes:
    • Add command line option "--debugger" for debugging purposes

As usual, we welcome your feedback on the mailing list.

Version 0.4.8 is released

October 03 2007 - User:Tfry

Version 0.4.8 of RKWard is available for download, now. The new release features changes all over the place, including new plugins, an integrated filesystem browser, and several bug fixes. Also optimizations were done to speed up some aspects, slightly, and to reduce typical memory usage, considerably. Many thanks to all who helped with the release. The full list of changes:

  • User visible additions / improvements:
    • New plugins: pie chart, dot chart, crosstabulation, two time-series tests, and basic linear regression
    • barplot plugin allow specification of custom labels
    • graphics export plugin gains option for EPS compatibility
    • CLT plugins allow drawing grid
    • commands run through the console from the script editor will now be added to the command history (this can be turned off in the settings)
    • object viewer also shows summary information, gains an update button, and MDI integration
    • add max.print option to R-Backend settings dialog * all file selection line edits gain filename-completion
    • add a basic file selector window
    • show the focus indication (thin red border) also for detached windows
    • tool windows can be closed and detached in the same way as regular windows
    • Messages, warnings, and errors for plugin commands are shown in the output, instead of in a dialog
    • new translation: Simplified Chinese (contributed by Roy Qu)
  • Bug fixes:
    • fixed: promise objects (created by delayedAssign()) directly in globalenv() would be forced early
    • make wrapper script work, when konsole is not installed
    • correct syntax highlighting for ::: and NA_integer_ and others
    • fixed: crash when editing a data.frame with logicals (logicals are still mishandled, but less severe)
    • fixed: would not work with R 2.6 * more compilation fixes for GCC 4.3
    • fixed: inserting / removing rows in the data editor in the presence of invalid fields in later rows would lead to a crash
    • fix some internal problems with enabledness/disabledness of plugin components
    • fixed: sometimes detecting created X11() windows would fail, esp. under high load
    • fix a crash with detached tool windows
  • Optimizations:
    • syntax highlighting is minimally faster for long outputs
    • some complex plotting plugins now start up noticeably faster
    • create the workspace browser only when it is first shown
    • add possibility to blacklist packages from fetching structure information. Package GO is blacklisted by default.
    • when fetching the structure of "promise" R objects, don't keep them in memory
    • optimize the function to retrieve the structure of R objects (for display in the object browser, and completion)
  • Miscellanious / internal:
    • silence some GCC 4.2 warnings
    • support for including files and snippets in xml files
    • add command line option --disable-stack-check for systems where R C stack checking is buggy
    • the modifier "not" for boolean properties returns a (negated) boolean sub-propery instead of just a string

NOTES:

  • R 2.6.0: Previous releases of RKWard will not work with the upcoming R 2.6.0. You need RKWard 0.4.8 (i.e. this release) in order to work with R 2.6.0. Note that when upgrading R after RKWard, you will need to recompile.
  • With the addition of the new filesystem browser, the shortcuts to show/hide the main tool windows have changed. The filesystem browser window can be toggled using Alt+2, the shortcuts for command log, pending jobs, console, and help search are now Alt+3 through 6, respectively, instead of Alt+2 through 5.
  • All commands run through the console are now added to the command history of the console, by default. This setting can be changed back to the old behavior (only commands *entered* in the console are added to the history) under Settings->Configure RKWard->Console.

Enthusiastic? Disappointed? Need help with RKWard? Your feedback is welcome on the mailing list.

Bugfix release 0.4.7a

May 07 2007 - User:Tfry

Recently, some problems have been discovered related to resolving some fortran symbols, on at least some systems. Since these can make RKWard crash even on simple operations, and not compile on some systems, a bugfix release dealing with these issues has been prepared. While at it, a number of additional bugfixes contained in the development version have been included, here, as well.

In detail, the changes are:

  • add sanity check for the detected stack limits
  • fixed: one some systems rkward would crash or not compile due to missing fortran symbols
  • fixed: starting the scatterplot plugin in wizard mode would crash rkward
  • tab-completion in the console will do partial completion, if all potential completions have a common start
  • fixed: file-name completion would always assume the home directory as the current directory
  • update turkish translation
  • compilation fix for FreeBSD (thanks to Thierry Thomas)
  • fixed: when executing commands line by line from the script editor, line breaks would be omitted

If you are experiencing any of the above problems, please download and upgrade to version 0.4.7a of RKWard.

New mailing list: rkward-users

April 04 2007 - User:Tfry

The past few months there has been a lot of active development on RKWard. The outcome of this - version 0.4.7 - is scheduled for release, next week. As a side effect, our main mailing list has become rather busy, with lots of discussion about development details. At the same time, the stats show a nice number of downloads, and hence a considerable increase in the RKWard user base.

For these reasons, it's time to create a dedicated users' mailing list. This list will be read by most active developers, and it will receive notifications about the most important steps of development (new testing versions and releases). However, instead of discussing low level details, this list will provide a better forum for discussing usage questions, but also for providing suggestions and feedback.

If you'd like to keep informed on all development details (and perhaps provide insights and contributions on that), you may want to subscribe to our "old" development mailing list. If you're mostly interested in questions of daily use, the new users' mailing list is the best choice. Or subscribe to both, if you don't want to miss a thing.

RKWard 0.4.0 released

October 17 2006 - User:Tfry

Once again, it's time to announce a new release of RKWard is available for download. Perhaps most importantly, this release enables you to browse the entire R workspace, including objects in R packages. In future releases this will allow us to implement helpful features such as code completion and argument hinting, so stay tuned for what is still to come.

The list of changes in 0.4.0:

  • Features / improvements:
    • many new distribution plugins
    • all distribution plugins now use a free-text field, allowing you to enter a vector of probabilties / quantiles
    • RMB option to search help on objects from packages in object browser
    • show tooltip information on objects in object browser
    • the object browser is updated automatically when needed
    • allow some more configuration in object browser
    • include all package environments in object list
    • add (ugly) items for functions and lists to object browser
    • when saving/loading the workspace, save / restore all windows (not just data editors)
    • add mismatching brace detection to syntax highlighting
    • RKWard should now be fully UTF-8 aware. All characters are passed to and from R reliably
  • Bugfixes:
    • another fix to cancelling during readline () calls
    • do not crash on call to "browser ()"
    • remember workspace url after save as
    • fix a long standing (but hard to trigger) crash while closing data editor window
    • fix "Open R Script File" filename ending filter
    • yet another crash on more than 100 rows bug fixed
  • Internal changes:
    • invalid values are stored in a separate attribute instead of changing the storage mode back and forth
    • storage mode for RKWard meta data was changed (see note below)
    • internal cleanups (partially to make porting to KDE4/Qt4 easier)
    • use more efficient data passing to synchronize object list

Please give the new release a try, and send your feedback to the mailing list.

Note: The way meta information (most importantly the descriptive variable labels in the data.frame editor) is stored was changed in this release. When loading workspaces created with earlier versions of rkward, this information will not be available (the data is not affected, however). To convert your saved workspaces to the new format, 1) open the workspace in question, 2) run the command "rk.convert.pre040 ()" in the RKWard R console. We're sorry about the inconvenience.

RKWard 0.3.7 is out

    • Improved syntax highlighting defintion including code folding
    • engine status bar label ("R engine busy/idle") now changes background color according to state
    • small improvements to command history in console

RKWard always needs user feedback to improve further, so please try out the new release, and tell us what you think on the mailing list.

Bugfix release 0.3.6

April 23 2006 - User:Tfry

Much sooner than expected, a new release of RKWard has been made available for download. Most importantly, contrary to our expectations of one week ago, RKWard 0.3.5 will not work with the upcoming R 2.3.0, so a new release was needed quickly.

Despite the limited time, a number of further bug-fixes and small improvements have made it into the new release. Here's a mostly complete list of changes:

  • Compilation / Installation:
    • remove configure options --with-r-share and --with-r-doc (obsoleted by improved wrapper script)
    • some fixes for R 2.3.0
  • Bugfixes:
    • clean up output of require (quietly=FALSE)
    • middle mouse pastes selection, not global clipboard in the console, as expected
    • make Ctrl+V work in the console
    • fix bug in scatterplot plugin
    • don't try to show higher numeric precision than is actually available
    • use KDE standard icons in object lists (need to be replaced by customized icons in the long run)
    • check for and handle some strange R parse errors that could crash rkward
    • several fixes to the distributions plugins
  • Improvements / features:
    • make Ctrl+C/copy work in output and help windows
    • allow empty input in readline ("R backend requests information") dialog
    • process R X11 events while modal dialogs (such as "R backend requests information") are shown
    • pressing Cancel in readline ("R backend requests information") dialog interrupts the command
    • prevent R-Object listviews (Varselector, Workspace Browser) from growing excessively wide
    • allow deletion of several rows at once in the data.frame editor and fix some bugs regarding deletion of rows
    • make Ctrl+C copy work in the code window of plugins
    • remove one level of menu nesting for save/load R Objects plugins
  • Internal changes:
    • remove debian dir from source distribution again (for better packaging)

As usual, we'd be interested to read your feedback on the mailing list.

Important Note: RKWard 0.3.6 can be compiled (and of course run) with R 2.1.x, R 2.2.x and the upcoming R 2.3.x. However, when upgrading from R 2.2.x to R 2.3.x, you will have to re-compile and re-install RKWard. Also, if your distribution currently ships a pre-release version of R, chances are, RKWard will not yet work with that version (but you may want to give it a try). You'll have either downgrad to 2.2.x temporarily, or upgrade to the final release of R 2.3.0 once available. To be precise, SVN revision 37824 is the first pre 2.3.0-version of R, RKWard 0.3.6 will work with.

Currently a pre-compiled .deb package of RKWard is provided for R 2.2.x releases. A .deb package compiled for R 2.3.0 will be made available as soon as possible.

We're very sorry about the inconvenience, but unfortunately, there is nothing we can do about it.


RKWard 0.3.5 is out

April 16 2006 - User:Tfry

Finally a new release of rkward is available for download. The focus of this new release has been on reworking the code responsible for dealing with plugins, and on fixing many small bugs. However, also a number of new features/improvements have been done since the last release. Most noteably, there are new plugins for Histograms and Boxplots, and for many distribution functions. A mostly complete list of changes:

  • Bug fixes:
    • give back focus to the script editor after running line/selection/all
    • clean up R temporary files on shutdown
    • fix crash with objects with quotes in their names
    • avoid leftover PHP processes if rkward crashes or gets killed
    • code display (for plugins) gets updated reliably
    • handle non-existing and non-local URLs
    • use a shell wrapper around rkward to do some setup just like R. This should fix a number of minor quirks (links) in help window
    • update tab caption for command editor if filename changes (i.e. saved as)
    • keep main window caption up to date
    • fix status bar
    • in trailing rows/columns of the data.frame editor, change background color, when selected
    • explicitely set LC_NUMERIC to "C" at startup. R does not work correctly with other settings of LC_NUMERIC
  • New features:
    • added syntax highlighting in the console
    • show info message, if retrieving context help fails
    • pressing Ctrl+C in the console resets a partial command, if any
    • backspace or del clear cells in data.frame editor
    • when switching between dialog and wizard interfaces, GUI settings are copied
    • add options to show help-search and R help index to Help menu
    • many new plugins by Stefan Roediger
    • indicate if a document in a command editor is modified (unsaved)
  • Compilation / installation:
    • configure: if not overriden, and $KDEDIR is not set, assume --prefix=`kde-config --prefix` instead of /usr/local/kde/
    • autodetection of R_HOME and related variables during configure
    • configure: use single configure option for location of R_HOME, and add check for libR.so
    • most of the time you will no longer need to specify options for ./configure
  • User Interface improvements:
    • reworded exit dialog box
    • remove some GUI clutter for Script File editor
    • rename "Command File" to "Script File"
    • rename "Command Stack" window to "Pending Jobs"
    • reworked factor levels editor
  • Assorted:
    • complete rework of plugins code
    • plugins can embed other plugins
    • yet more code cleanups

Please give the new release a try, and send your feedback to the mailing list.

Important Note: If you see the message "Error: C stack usage is too close to the limit" on the console, this is due to a small but grave bug in R. This bug is present only in a few pre-release packages of R 2.3.0, but some of those are floating right now. If you encounter this bug, you will have to either downgrade your version of R, or wait until fixed packages are available for your distribution. If in doubt what to do, ask us for advice on the mailing list.

RKWard 0.3.4 released

November 2005 - User:Tfry

A new version of RKWard is now available for download. Changes include:

  • Bug fixes:
    • fix installation of standard_plugins.pluginmap
    • make "up"-button work in R-backend repository settings
    • Settings->Command Log->show/raise window working again
    • assorted other bugfixes, including fixes to linkage, fixes for crashes, etc.
  • New features / improvements:
    • real time display of command output in the console
    • automatically scroll command log to the bottom when new lines are added
    • back/forward navigation in help pages
    • can print help pages and output
    • better handling of errors while installing packages
    • allow loading/saving of command history (console commands)
    • allow interrupting current command running in the console via Ctrl+C
    • add "Command stack" window for advanced control of R backend (cancel commands, pause chain, view stack)
    • allow configuration of many R options in Settings->R backend
    • avoid adding incomplete (multi-line) Console commands to the Command Log
  • User interface:
    • less verbose output in command log (removed "issuing command", etc.)
    • help-, output-, and editor-views can be detached to separate windows
    • allow to bypass startup dialog
    • limit number of lines to display in console and command log (user setting)
    • remove menu clutter from help window, and output window
    • add (meaningful) context menu for console
  • Translations:
    • updated French translation
  • Internal / technical changes:
    • include debian-dir in source distribution
    • use KXMLGUI for placing plugins in the menu (mostly an internal change, but menu placement should remain sane, when active window changes, now)
    • modifiy rkward.desktop to always start rkward in a terminal. The backend sometimes behaves strangely, if this is not done
    • use available.packages instead of CRAN.packages (deprecated in R 2.2.0)
    • more code cleanups

Please check out the new release, and tell us what you think on the mailing list.

Note: If you have previously been running version 0.3.3 of RKWard, you may have a bad saved setting for the location of .pluginmap-files. In this case RKWard will complain about missing plugins on startup. In order to fix this, go to Settings->Configure RKWard->Plugins and remove all entries for .pluginmap-files. After that, quit, and restart RKWard. The correct location of the standard plugins should then be autodetected.


Bug in RKWard 0.3.3

October 12 2005 - User:Tfry

One fairly important bug went unnoticed, when preparing the 0.3.3 release. An important file did not get installed, and this will lead to RKWard being unable to find its plugins. Fortunately, this can be worked around by simply installing one additional file.

Download this file. It needs to be installed to $prefix$/share/apps/rkward/standard_plugins.pluginmap, where $prefix$ is the directory you specified as --prefix when running ./configure. So, for example, for debian, it has to be installed to /usr/share/apps/rkward/standard_plugins.pluginmap

Sorry about the inconvenience.

RKWard 0.3.3 is released

October 10 2005 - User:Tfry

Together with the new website, a new version of rkward is now available. Changes in the new release can be grouped roughly in these categories:

  • Feature additions: Options to archive downloaded CRAN packages, and to select custom repositories. Context help in the console via F2.
  • User interface: The user interface is now somewhat more consistent. For instance, all windows can be closed with Ctrl+W, and the menu options get updated according to the current window. New icon by Marco Martin
  • Backend enhancements: A number of internal changes have been made. What should be noteable to regular users is that RKWard now behaves sanely, if you run commands like "fix (myfunction)" or "help (print)". Also warnings are now displayed correctly in most cases.
  • Plugins: A first step has been done to rework the plugin infrastructure. The next release will see further improvements
  • Cleanups & Bugfixes: A number of bugs has been fixed, many sections of dead code have been removed, several areas of the sources are much cleaner, and more well-documented, now.

For a complete list of changes, please see the changelog in the download section. Please give the new release a try. We welcome all feedback to the mailing list.

New website for RKWard

October 10 2005 - User:Tfry

Unless you're here for the first time, you'll have already noted: Finally the old RKWard website has been replaced with a new, pretty, and flexible website. A very big thank you goes to Yves Jacolin, the one who worked hard to create it!

The new website is divided into three main sections, you can navigate between using the links on the top of each page. The User section contains usage information on RKWard, screenshots, and FAQ. Developers will find additional information in the Development section. Finally, a new Wiki is available, where users can help us create new documentation on RKWard, but also discuss translation, and development issues.

Also, you will note that the new website is designed to be multi-lingual. So far, little has actually been translated, but we will work hard on providing the most important information in several languages (work has started on a French translation). If you can help with this, please contact us on the mailing list. Old news items - tfry - On the 07 October 2005 -

With the new website layout, we switched to our own news system. This new system allows us to post news in a number of different categories, and filter them according to those categories - such as news of interest to users vs. news for developers. Also, news can now be translated. Older news items, posted prior to the switch, are still available from the sourceforge archive.
