[R] Running R from a CD on Windows?

[Gabor Grothendieck]

There is a batch script, rgui.bat, in batchfiles, see home page at
batchfiles.googlecode.com, that will search the registry and a
few other places for R and start up R if it can find it.  It does
not search  CD's automatically but that would be simple to add.
