That is no use. Use grass-stats if you need help with the R-GRASS 
interface, the developers do not read other channels regularly.

Work with forthcoming (soon to be stable) GRASS 7, not with the 
development version.

So download:

http://download.r-forge.r-project.org/bin/windows/contrib/latest/spgrass7_0.1-0.zip

and install from local zip file (untried). None of the developers uses 
Windows, so this isn't a priority. Alternatively, install R-tools foe 
Windows and then install the source package.
