Shouldn't that be ...
(setq inferior-R-program-name "/cygdrive/c/R/R-2.13.0/bin/i386/Rterm.exe")
If that is not the problem or it does not help, then read on for more
radical tips (heavy XEmacs users look away now)...
Is there some reason that you need to use XEmacs? I have never been a
fan of XEmacs on Windows. I find XEmacs to be pretty serviceable on
Linux and Unix, but I have never liked the Windows or Mac OS X versions.
Some times switching from XEmacs to Emacs (or vice versa)
will fix these kinds of problems.
