Excelsi-R Files

Excelsi-R User-level Changelog

-----------------------------------------------------------------
v0.8 March 8, 2016

Fixed Unicode support, so Excelsi-R should now work with multiple
languages.  This requires that the Rserve server be configured to
encode in UTF-8 (this can be specified via Rserve command line or
configuration file).

Included the lookup2d utility function, which had been omitted
accidentally before.

-----------------------------------------------------------------
v0.7 April 30, 2015

Fixed a crash that would happen if you tried to bring an empty string
("") from Excel into R.

Excelsi-R add-in will now preserve cell formatting when a range output
varies in size between runs.  Previously the formatting would be
cleared for the new cells required.

Companion R package ExcelsiR now allows graphs to be explicitly sized
(both in inches and dpi).

Companion R package ExcelsiR includes a CharStr function to inspect
objects of an arbitrary type

-----------------------------------------------------------------
v0.6 November 11, 2014

This is a large new update to Excelsi-R.  The project's direction has
changed---the focus is now on running Excelsi-R through program blocks
and not on using the Rassign() and Reval() functions inside Excel
cells.

There have been a number of features added to support this use and
improve the user interface.  However, the auto-resizing functionality
has been removed.

------------------------------------------------------------------
v0.5.1 October 7, 2013

Fixed a bug the "Copy as R Code" feature could have when the selected
region could include empty cells.

------------------------------------------------------------------
v0.5 April 13, 2013

Added button to copy Excel cells as R code.  Made some preliminary
efforts to standardize moving data using the three different methods.

------------------------------------------------------------------
v0.4 November 24, 2012

Added graphics functionality---it is now possible to embed an R graph
into an Excel spreadsheet, and have the R graph get automatically
recalculated as the Excel data changes.

The Excelsi-R add-in now comes with an ExcelsiR R package that you can
install on the R side.  A function called ExcelsiRGraph exported by
that package is necessary to export graphs.  The package also includes
functions that you can run from an interactive R session to move data
to and from the clipboard or Excel.

------------------------------------------------------------------
v0.3 November 11, 2012

Added auto-resize functionality!  Now when you run reval() in a cell,
that formula will be automatically resized to match the size of the
returned array.  Because R is so vector oriented, I hope this will
make Excelsi-R much more efficient to use.

Ported Excelsi-R to compile using Visual Studio instead of GCC, for
better binary compatibility with Excel.

------------------------------------------------------------------
v0.2 April 18, 2012

excelsir.dll is now statically linked with some base libraries.  If
you got a "File not Found" problem with the previous version this
should fix it.

EReval and ERassign renamed to Reval and Rassign.

------------------------------------------------------------------
v0.1 April 14, 2012

Added remote operation dialog: you can point Excelsi-R to Rserve
running on a remote computer.

Evaluated data frames with character rownames are now displayed.  You
can assign a dataframe with rownames by putting them in the (rownames)
column.

R factor objects are now supported and automatically converted to
characters.  Before they would just be displayed as integers.

Improved NA handling.  R NA's should come through now as Excel #N/A!
errors and vice-versa.

Assorted cleanups in installer and add-in

------------------------------------------------------------------
v0.0 April 2, 2012

First version, everything's new!
