[R] Help with Kriging

[Paulo Justiniano Ribeiro Jr]

Jennifer

The algorithms in geoR are (at least up to now) focused on kriging with 
global neighbourhood.

You you would like to use moving neighbourhood based on distances my nest 
advice is to use a function from another package such as RandomFields, 
gstat, or any other geostats package

Best
