Dear List,

I hope this is not a redundant question.  I tried to find the issue from
the previous lists but could not find although there are several comments
about comparing two species distribution in the same area and coordinates.

I have a data set with species counts in a study area, however, the GPS
location is slightly different from species to species.  The sampling was
conducted in a grid pattern covering uniformly the area.

My question are:
Is there any package(s) and/or way(s) to compare spatial distribution of two
species with different coordinate readings in the same study area?
If so, is there any (potential) problem(s) in doing that?

Thanks for your any comment and suggestion in advance!

Steve
