There are different understandings of PATH in MSYS (the GRASS shell) and 
Windows. To start R, it is safest to give its absolute path, unless you 
know definitely that Rgui.exe is on your PATH. You may see a Flash film 
at:

for an example of starting Windows Native GRASS with an absolute path. 
Note that the R_LIBS environment variable may also need setting.

Hope this helps,

Roger
