If your sites are generally more than one per cell, kernelling with
s.kernel or interfaced with one of the geostats tools in R.
Note s.kernel isn't built by default in 5.0/5.3, but is built as
v.kernel in 5.7.

If your sites are generally less than one per cell, you might try doing
something like "distance to the nearest site" using r.cost, then maybe
r.neighbors for smoothing if needed for a hardcopy. Then use a MASK and
r.univar for mean distance to a site from within your study area.


but maybe v.kernel is good either way, I'm no expert. To me site
densities <1 don't make much sense though..
