I think it is easy.  The Windows R installation puts a shortcut "R
2.12.1.lnk" on the desktop.
That might be sufficient as is.

That shortcut could also be copied to any arbitrary place, say c:/program
files/R.lnk, and
on 64-bit machines, we could also have R32.lnk and R64.lnk, with R.lnk
pointing to
the 32-bit system as Martin suggested earlier in this thread.  The shortcut
can be
programmatically executed from the MSDOS cmd window, and from the shell exec
mechanism.
