Ah. I didn't know that windows internationalised that. 

For me (getenv "ProgramFiles") returns the right location though. So

 (concat (getenv "ProgramFiles")

Should return all the R directories in the standard place. For me that is...

("." ".." "R-2.5.1")

Failing that 

(executable-find "R.exe")

which is...

"c:/Program Files/R/R-2.5.1/bin/R.exe"

will work iff R is in the path. After that, 

HKEY_LOCAL_MACHINE\Software\R-core\R\Current Version

gives the current version


gives it's location. w32-regdat gives access to these values, although this
also requires an external executable. 

If I get the time, I'll try and write some lisp to get this to work.
