There is probably a more eloquent way, but I have taken a vector
watershed boundary, converted to a raster, and set as mask. Then used
a r.mapcalc expression like newMap=oldMap+0.

It is as simple as this:
d.zoom || g.region
g.region -p

Hi Stephen,
I suggest you use spgrass6 package on R,
set your g.region using system(g.region n= s= w= e=)
on R and use readRAST6 to load your map
as SGDF. Of course, if you are under windows,
you know that depending the size of your grid
you will get troubles :-)

Stephen,
Yes, you can.
I am aware of r.topmodel in GRASS, but I am much more familiar with R
than GRASS, and the GRASS documentation is not as comprehensible as
that for R -- This is just because of my own bias and does not reflect
on anybody but me. I would love to try it in GRASS but I think I need
a tutorial. Any
