Changelog

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
