Ok. The work-around I can grow accustomed to, or I might fall back on GRASS5.4 if that works.
I wonder if another problem that cropped up is somehow related to the first. Using interp=TRUE I managed to import a raster map to R. But when trying to plot it, I get the following: > plot(G,tt$rb1) Error in reverse(G) : cannot allocate vector of length 1086556160 ??? Thanks for the help, Steve --- Steven T.
