rkward-devel Mailing List for RKWard - GUI for R

 Occured after updating r-base July 1, 2018 and sent the massage


'The R engine has encountered a fatal error:
unable to initialize the JIT
The R backend will be shut down immediately ...Since this should never happen, please write a mail ...and tell us, what you were trying to do'


It happened at the first use of RKWard after the update of r-base July 1, 2018 in Linux Mint 17.3.


Hope you have a solution to my first scratch in a great product.

Hi,

      Please look into the screenshot picture. I opened rkward for the
first time and that is the message it shows. I can't load any data or do
anything here. Please let me know what the problem is.

Karthy

Hi there!

I'm ubuntu user (12.04, 64-bit).
After update R to version 3.2.5 (2016-04-14), RKWard was unable to be used.
Before and after that, RStudio works normally.
Do you know anything about that?

So many thanks in advance.

Best wishes,

Mariano

Betreff: KDE Emerge emerged as Craft
Datum: Montag, 21. November 2016, 10:22:24 CET
Von: Hannah von Reth <vo...@kd...>
An: kd...@kd... <kd...@kd...>, kde...@kd... <kde...@kd...>

The KDE Emerge tool got a new name.
Not only that, Craft is capable of so much more than just building KDE on 
Windows.

Craft is an open source meta build system and package manager. 
It manages dependencies and builds libraries and applications from source, on 
Windows, Mac, Linux and FreeBSD. 

Read the announcement[1] and start Crafting!

Visite the new Community Wiki[2]
or our new repository[3]

Kind regards,

Hannah

Dear Sir/Madam

I am using RKWard on Ubuntu Mate having used it a lot on Windows.  I don't seem to be able to install ggplot2 though.  I love RKWard, so I would hate not to be able to use it!

I am using R version 3.2.2 (2015-08-14) -- "Fire Safety"
Copyright (C) 2015 The R Foundation for Statistical Computing
Platform: x86_64-pc-linux-gnu (64-bit)

This is what I get.  Sorry it is so long, but I am not sure what you need and I am not a computer buff!

Many thanks

Edward

Hello,

I was running some graphics-saving code, and I got this error:

Connection closed unexpectedly. Last error was:
QLocalSocket: Remote closed
The R backend will be shut down immediately. This means, you can not use 
any more functions that rely on it. I.e. you can do hardly anything at 
all, not even save the workspace (but if you're lucky, R already did 
that). What you can do, however, is save any open command-files, the 
output, or copy data out of open data editors.
Quit RKWard after that.
Since this should never happen, please write a mail to 
rkw...@li..., and tell us what you were trying to 
do, when this happened. Sorry!

I had the following libraries loaded:

* plyr
* dplyr
* reshape2
* ggplot2
* scales

I was looping through a list of 2-length characters to generate pairwise 
plots.  Here is the code that was running near the end:

 > for (pair in support_pairs){
+   v1 = pair[1]
+   v2 = pair[2]
+   input_make_percent = all(na.omit(df[,v1])>= 0 & na.omit(df[,v1]) <= 1)
+   output_make_percent = all(na.omit(df[,v2])>= 0 & na.omit(df[,v2]) <= 1)
+   if (input_make_percent) {
+     v1p = scale_x_continuous(label=percent)
+   }
+   else{
+     v1p = NULL
+   }
+   if (output_make_percent) {
+     v2p = scale_y_continuous(label=percent)
+   }
+   else{
+     v2p = NULL
+   }
+   graphic = ifelse(is.factor(df[,v1]),geom_bar,geom_point)
+   png(fn_make(paste0(v1,'_',v2,'_','support.png')))
+   print(
+ 
ggplot(df,aes_string(x=v1,y=v2))+graphic(stat='identity')+geom_smooth(method='lm') 
+
+     xlab(input_descriptions[[v1]]) + ylab(results_descriptions[[v2]]) +
+     ggtitle(titlify(paste0(input_descriptions[[v1]],' vs. 
',results_descriptions[[v2]]))) +v1p + v2p
+   )
+   dev.off()
+ }
--- interrupted ---

I realize there was a bug (geom_smooth should not be used when I use 
geom_boxplot). When I removed this bug, the issue no longer persisted.

Here is the curious thing: When I added a print(pair) line in the second 
loop (where the error occurs), it did not initially print, but after the 
error was thrown, it started to print out each of the pairs, and when it 
finished, I could use the console again and resume work normally (even 
when I didn't remove the previous bug).

When I added print(1), print(2), print(3), print(4) to various points in 
the code, it did not thrown an error at all.  When I removed the 
additional print statements (whether they were inside the png() block or 
not), the error persisted.

This error occurred using Version 0.6.1, and I am running it on Ubuntu 
14.04 LTS.

I will send any additional information I can (or if I've found a way to 
resolve the issue.

Best,

Max Candocia

Hello team,

 

A new install of rkward crashes the R backend when it launches.  Rkward is
running on a Ubuntu 14.04 ("Trusty) 64 bit system.  The R version on the 64
bit machine is not known and is identified by the R team as "R under
development (unstable)".

 

As a point of reference, an installation of Rkward does NOT crash the
backend on a 32 bit Ubuntu 14.04 box. This version of R is 3.2.2.

 

Any help would be appreciated.  It's a nice software.  Compares favorably to
Rstudio.

 

Regards,

Mark Allyn

this looks like the R backend is crashing. This could be a problem with
RKWard or it could be a crash in R / one of the packages involved. A
useful first approach to narrow the problem is to try running the same
thing in a plain R terminal session. If needed, you can refer to
RKWard's "Command Log"-Window and copy and paste all the steps
involved.

If you get crahes, there, you'll have to debug your R packages.
Typically, gctorture() helps a lot. If you cannot reproduce the crash
outside RKWard, please do get back to us, so we can track down and fix
the issue in our code.

Thomas

Hi,
Running Ubuntu precise LTS thru Vbox on an now oldish Toshiba laptop.
Graphics card won't let me upgrade to more recent Ubuntu.  Consequently I'm
using rkward 0.5.7-2build1.
<https://launchpad.net/ubuntu/+source/rkward/0.5.7-2build1>

Last night I upgraded R to 3.2.2 from 2.15 ish to run more recent packages.

When starting dialogue 'R-engine has died' (graphic attached). The dialogue
said I should email you.

I've re-installed 0.5.7-2 a couple of times.  I will now be trying to
install and run version  0.6.2.

This small piece of work is all I need to get rid of my PhD.  Hope it can
be easily surmounted.

Here is my guess:

- You are running on Windows
- You installed the "Complete installation bundle", version 0.6.2 of
  RKWard

Please make sure you run the "rkward.exe"-file contained in this. Do
not run "rkward.frontend.exe", or - in case you have installed over a
previous installation "rkward.bat".

If you want a better guess, please provide more detail (which
operating system, how did you install, etc.). If possible at all, please
write in English. See http://rkward.kde.org/bugs .

Status
------

This change has been marked as submitted.


Review request for Rkward.


Repository: rkward


Description
-------

So we can shut down the svn repo on SF.net (actually not shutting it down, but marking it as out-of-date)


Diffs
-----

None. Which is the reason for this review request. (Well, another reason is that I wanted to test our reviewboard setup).


Thanks,

Backend process has exited with code -1073741515.

This warning appears when the program is loaded.I impedes load jobs.Thanks.Ruben

Dear developers,
I got this error when running rkward on Ubuntu 12.04.

I was trying to install R Bioconductor, which required upgrading to the 
most recent R version (just adding the apt repo in Ubuntu, installing 
the packages r-base and r-base-dev)
and then installation of several packages through the command line 
(running sudo R ...)

The error reads:
Connection closed unexpectedly. Last error was: QLocalSocket: Remote

Should I reinstall rkward or something?

Dear subscriber of rkward-users,

as part of our migration from SF.net to KDE.org, we're also moving our
mailing lists. rkw...@li... will become
rkw...@kd... .

I will move your subscription to the new list, then deactivate the old
list. Note that individual settings such as receiving mails in daily
digests will be lost in the transition, and you will have to re-set
these. Sorry about the inconvenience. You should receive a mail
containing a new mailing list password, and a link to the subscription
configuration page shortly after this mail.

If you do not receive a notice of subscription to the new mailing
list, or if you need any other assistance, just let me know.

Regards
Thomas

Probably the cause of the problem is just that, then: The location you
are trying to install to is not writable (with your current user
permissions). Before anything else, try this in the console:

  .libPaths (c ("D:/mystuff/Rlibs", .libPaths ())
  install.packages("R2HTML")

Where "D:/mystuff/Rlibs" should be an existing and writable folder. If
this works, add the call to .libPaths(...) to Settings->Configure
RKWard->R backend->"Further (option) commands to run in each session".

If problems persist, please let us know.

Thanks!
Thomas

Hi!

This is to let you know that mailing lists on SF.net are apparently
suffering from silent loss of some mails since approximately one week.
I know of at least one post that is missing from rkward-devel, but
there is no way of telling how many messages got lost. Other projects
are affected, too.

If you have recently posted to rkward-devel or rkward-users, please
check the list archives to make sure your mail arrived. If it did not,
consider re-posting. Links to the list archives:

In somewhat related news, our lists will migrate to kde.org, shortly.
I'll let you know the details, then. In most cases no action will be
needed on our part. Given the timing of these two events I just want
to point out that the upcoming migration is neither a cause, nor a
consequence of the mail loss - although this new issue, and the
disturbing lack of support response from SF.net is certainly another
reason not to regret the move...

---Problem description---





I cannot install any package


Not even through console and after put a known issue:




> "setInternet2(TRUE)"
[1] "setInternet2(TRUE)"
> install.packages("R2HTML")
Warning in install.packages("R2HTML") :
  'lib = "C:/Program Files/R/R-3.1.2/library"' is not writable








-What - in detail - did you do directly before you encountered this problem?



I have intalled last versions of R (3.1.2) KDE and Rkward in woindows 8.


 I got just one issue. When I tried to install rkward, it said that could not be possible to open this file " 
libgcc_s_sjlj-1.dll
I omited it and then It was installed.
When I run rkward i got the following message inside Ms-dos window (black window):
warning: QFileinfo: : absolute path: constructed with empty filenamewarning: QFileinfo: : absolute path: constructed with empty filenamewarning: QFileinfo: : absolute path: constructed with empty filenamewarning: QFileinfo: : absolute path: constructed with empty filenamewarning: QFileinfo: : absolute path: constructed with empty filename




But the progam runs









-When you try to repeat the above, does the problem occur again (no, sometimes, always)?



It happen always








-If applicable: When doing the same thing in an R session outside of RKWard, do you see the same problem?



I do not know how to use R





-Do you have any further information that might help us to track this problem down? In particular, if applicable, can you provide sample data and sample R code to reproduce this problem?

###Please fill in###




-RKWard is available in many different packagings, and sometimes problems are specific to one method of installation. How did you install RKWard (which file(s) did you download)?

###Please fill in###

as it happens, rk.plugin.component() already does this if "about" is an 
<about> node. rk.plugin.skeleton() just strips this down to the component 
name, so it definitely needs a new switch to change this.

Hi!

So I have just imported the rk.power plugin from our external_plugins
repo, into the "main" sources. The import did not quite work quite as I
had hope, this time around, but essentially all relevant history was
preserved in the import.

Some issues / questions:
- What do we do about the imported plugin in the external_plugins
  repository? In general all changes should go to our main repo from
  now on, so the plugin should be removed in external_plugins. OTOH, we
  may want to defer deletion until RKWard 0.6.3 is actually released
  with the plugin - or even some time longer. Meik, as the manager of
  our plugin packages: What's best for your workflow:
    - Delete the plugin in external_plugins, right away
    - Keep the plugin in external_plugins for some time, but move it to
      some subdirectory ("imported")
    - Keep the plugin in external_plugins in its current path?
- The development version of RKWard supports plugins from different
  sources overriding each other (the one specified to have the highest
  version, _and_ compatible with the runtime version of RKWard will
  "win"). Of course, this works for plugins having the same id, only.
  Now, as an "official" plugin, the power plugin has the version of
  RKWard (i.e. will have 0.6.3), and id "rkward::power_analysis". Would
  it make sense to adjust the id on the current (external) plugin
  package, so that users that have installed it will not get a
  duplicate menu entry (after they have updated it)?
- Inheriting the version number from RKWard is a side-effect of
  rkwarddev writing <about>-info to the .pluginmap, instead of the
  plugin .xml. In general that is a good idea, too, unless - as in this
  case - no pluginmap is being generated. Is there a way to control
  this, already?
- I placed the plugin in analysis.pluginmap. As written earlier, if we
  have a good idea on just how to split up plugins in a meaningful way,
  that can still be changed. However, having separate pluginmaps for
  each and every plugin (i.e. > 100 pluginmaps) would have quite
  an impact on performance (and would be somewhat questionable,
  usability-wise, too, IMO). So, for now, I keep following the "big"
  pluginmap approach. Meik, with the new plugin management UI, and
  rk.set.plugin.status(), do you still consider this an issue?

Hi all!

Somehow I forgot to drop you a note, but if you have visited the
project web site, recently, you will have noticed, that the main web
pages are now at http://rkward.kde.org - and much faster, esp. as far
as editing is concerned.

Time for the next step in our migration: Mailing lists. We currently
have:

- rkward-devel. 67 subscribers, archive dating back to the very
  beginnings of RKWard. Our primary mailing list.
- rkward-users. 148 subscribers, created in 2007. Less active than we'd
  originally hoped for, but seems to be quite popular for subscriptions.
- rkward-cvs. 11 subscribers, created in 2004. Receives code commit
  messages.
- rkward-tracker. 10 subscribers, created in 2005. This currently
  receives notifications of bug tracker activity, and of daily build
  failures.
- rkward-announce. 9 subscribers, of whom 2 are also subscribed to
  rkward-users (and mails are fowarded to rkward-devel and
  rkward-users), created in 2011. For release announcements, and calls
  for translations.

I'd like to propose the following migration plan. Does this sound
reasonable to you?

- rkward-devel is migrated to kde.org including all subscribers and the
  mailing list archive. rkw...@li... is set up
  to forward to rkw...@kd..., and will be kept around for some
  time.
- rkward-users is migrated in the same way.
- rkward-cvs and rkward-tracker are merged into one list
  "rkward-tracker". This will continue to receive commit-notifications
  and daily build failures. Bug tracker activity will be directed to
  rkward-devel in the future. Since these two lists were never meant
  for manual posting, the old lists can be shut down rather quickly.
- rkward-announce is dropped, as it does not seem worth the effort.
  Calls for translations will be sent to kde...@kd... (where our
  translations are now managed). Calls for testing will be sent to
  rkward-devel and rkward-users as before. For those who are interested
  in strictly release announcements, only, I suppose the best hint will
  be to subscribe to the RSS feed on freshcode
  (http://freshcode.club/projects/rkward). Other ideas?

Lists may have to be set read-only during migration, briefly. We'll try
to make any such transition period as short as possible.

Thomas

well, while touching on various areas of the code, I'm trying to work
on some of your feedback. Right now, I'm working to add i18n() to the
distribution plugins. And - as this will mean touching quite a bit of
that code - I'm wondering how to best address your comments regarding
those.

As a small bit of background information, IIRC, Stefan
originally modeled these dialogs on Rcmdrs example - many years ago.

You mean the p and q dialogs (pbinom, qbinom), right? Clearly for some
things, default values do not make too much sense. For "vector of
probabilities/quantiles", quite obviously so. For number of trials,
arguably, too - but that would mean it cannot be represented in a
spinbox (which simply does not have a "blank" value). For probability
of success in each trial, .5 sounds like a sensible enough default to
me, even if you are quite likely to adjust it.

So what are your thoughts on how to deal with this (also for all the
other distributions)?

Well, what I have in mind so far is the following:
- Merge probabilities and quantiles plugins into one (which could also
  calculate density), with a <radio>-control on top to select the mode
  of operation (
    calculate:
     O probabilities of given quantiles
     O density at given quantiles
     O quantiles for given probabilities
  )
- For the discrete distributions, add a UI label below this, reading:
  "Note: Quantiles correspond to number of successes in 'size' trials in
  the context of the binomial distribution" (and appropriately for the
  other discrete distributions, or at least the ones I understand).
- Change the input of probabilities / quantiles to use a
  <matrix>-element (i.e. a column of spreadsheet cells)
- This will be empty by default.
- Change the output to be tabular, i.e. a table with columns
  for quantiles and probs (or densities), and rows for each input value.

Does that sound like a useful plan?

Perhaps you simply forgot to adjust the id of the embedded plugin in
<connect>, when moving it to outside the optionset? The following works
for me:

<!DOCTYPE rkplugin>
<document>
        <code file="example.js" />
        <logic>
                <connect governor="x.available"
                    client="levels.variable" />
        </logic>
        <dialog label="Example">
                <varselector id="vars" />
                <varslot id="x" source="vars" label="Select variable"
                    num_dimensions="1" required="true" />
                <embed id="levels" component="rkward::level_select" />
                <valueslot required="true" id="values" label=""
                    source="levels.selector" />
        </dialog>
</document>

(Although, admittedly, the <valueslot> seems to be quirky in that it
does not show in red, initially; I'll look into that.)
