Please see my reply on the GRASS statistics list:

http://lists.osgeo.org/pipermail/grass-stats/2008-July/000833.html

verbatim:

"On my native Windows GRASS, 6.3.0 release, TclTk (wish) interface, I 
enter the full path to R - either "C:/Program Files/R/R-2.7.1/bin/R" 
(command line) or "C:/Program Files/R/R-2.7.1/bin/Rgui", and click either 
"Run" or "Run (background)", in the window named "Output - GIS.m", bottom 
pane.

You can find the correct path for your R in the properties of the R 
desktop icon. Use quotes if the path contains blanks, and forward slashes 
to avoid back slashes in the path being misinterpreted.

I have R_LIBS set as a user specific environment variable, so don't need 
to add this."

Refer to the other list link for the original question.

Native GRASS for windows is very new, but all the documentation applies 
once you find out how to start R in the right place. The Cygwin port is 
much more like OSX and Unix/Linux. Another version of native GRASS ships 
with QGIS for Windows. Since there are so many varieties, documenting how 
to proceed is far from easy.
