[R-sig-Geo] Kriging

[Alemu Tadesse]

Dear All,

I was trying to understand the spatial variability of a variable over a
region (variogram and kriging). I have attache the file for you to have a
look if ONLY you have a time. I am not familiar how R is computing
variogram and ultimately kriging. I read couple of papers and I had
difficulty to understand them. I really appreciate your help. For most of
you this might be a very trivial problem.

Thank you in Advance for your time and help.

Best,
Alemu
