Hi !

Sorry for my ignorance. I have two questions:

1) which is in R the function to make a covariogram of spatial data ?

2) does anyone know if there exist the possibility in R of performing
kriging with an arbitrary covariance function ?

If I have well understood the Krig procedure offers only three
possibilities (expcov, gauscov and sphercov) that are the common models
for stationary and isotropic processes.

Thanks,
Paola.
