[R-sig-Geo] rgdal and grass rasters

[Jonathan Greenberg]

Hmm, I'm trying to use the raster package via rgdal to access these
files -- I'm trying to avoid having to export then to another format
(I'm dealing with gigabytes of rasters), although I suppose I could do
this.  Does spgrass6 "enable" rgdal to access GRASS rasters, or is it
its own standalone program?  How does the base gdal package work with
grass rasters?
