Yes. Example: GRASS 6.4.0svn (nc_spm_08):~ > cat R_batch_nc.R library(spgrass6) mydem <- readRAST6("elevation") summary(mydem) To run it inside GRASS, do GRASS 6.4.0svn (nc_spm_08):~ > R CMD BATCH R_batch_nc.R The standard output result is stored in R_batch_nc.Rout. Of course you can also generate new GIS data in R and write them back to GRASS with writeRAST6() or writeVECT6(). Hope this helps, Markus PS: Yes, I am also suprised that the GRASS Wiki isn't full of useful scripts calling R in GRASS in batch mode... _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
