You have to modify you path, adding the directory containing R.exe so
that Windows can find R.

Alternately you can download R.bat from batchfiles.googlecode.com and
place it anywhere on your path to avoid having to modify your path
itself.  It will find R from the registry and run it with the same
arguments.
