Both GRASS 5 R package "GRASS" and GRASS 6 R package "spgrass6" work with 
cygwin. They work slightly differently, with "spgrass6" working just like 
Mac OSX/Linux/Unix - start the R text console inside GRASS from the text 
console prompt - start GRASS as $ grass -text, then start R as Rterm (the 
non-GUI front end). Rterm may need its full path to start. 

If the R packages are installed in an extra library (outside the install
tree), you may also need .libPaths() to add that directory to R's search
path for libraries once R is running.
