Odp: (senza oggetto)

Hi
I found that variogram is a function in spatial library. I tried

??variogram
library(spatial)
?variogram

I used an example and I did not have any problem with it.

data(topo, package="MASS")
topo.kr <- surf.ls(2, topo)
variogram(topo.kr, 25)

I do not have gstat available but from documentation seems that there 
shall not be any problem and that there is even example how to use it.

PLEASE do read the posting guide 

http://www.R-project.org/posting-guide.html

and provide commented, minimal, self-contained, reproducible code.

Regards
Petr
