[R] which package for spatial autocorr.

[Prof Brian Ripley]

I think you are looking for the spatial correlogram or variogram.  Try
help.search("variogram").  There is a long list, and of those

fields, geoR, gstat, sgeostat, spatial

look the most relevant. As spatial ships with R and is simple I would 
start with that.
