[R-sig-Geo] Read and write GRASS rasters without GRASS installed

[pgalpern]

Could anyone tell me if it is possible to read and write GRASS rasters 
(compressed) in R without having GRASS installed?  raster() will not do 
this directly.

Could readRAST6 in spgrass6 be used to do this?  It seems that is 
should, using the useGDAL option.  I have been unsuccessful, am I 
missing something?

Thank you,
Paul
