We're starting work on an R package and corresponding S-Plus library
to help programmers write software that will work in both systems.
Some descriptions and downloadable software are available on the
Omegahat web site, at
http://www.omegahat.org/SLanguage/
The strategy, as described there, is to be as back-compatible within R
and within S-Plus as possible, but provide tools and guidelines to
smooth over inconsistencies between the two implementations of the S
language.
The tools will include both S language and C/C++ support. It's
starting off with the functions that access objects (get, etc.), a
couple of tools for dealing with language objects, and a bit of
miscellany. More to come shortly.
If you're experienced or interested in writing software targeted to
both R and S-Plus, please take a look at the package. It's at a very
early stage, and comments, suggestions of what should be in there, or
(especially) contributions are very much needed.
