This "add-on" is not maintained or checked by its authors against current
GRASS or R, and should only be used by people knowing shell scripting and
R very well. My guess is that $nugget is not defined, as:
line 115: nugget=$GIS_OPT_nuggetv
where I think the v is a typo. However, this is just a guess. The code is
almost impossible to read, and does not use facilities in current
spgrass6, which would have simplified setting up the prediction raster.
Please do try to do this directly in R, it will save you a lot of time and
heartache!
