You saved my day. Only took me an hour to understand that i have to un-#
Sys.setenv(PATH=WPATH1) from your example ...

I can imagine that this is a problem for quite some people wanting to
utilize GRASS from within R with an OSGEO4W-install. Should find it's way
into some help page maybe...

So thanx for sharing
Cheers
Bernd
