Hi,

I 'll try to tell more about what  I 'm doing.
I a exploring the variance of climatic data. These are anisotropical and I
need to know the average semivariance along each azimuth transect to be
able to choose best directions for the variogram input as the angle should
be the azimuth of the direction of maximum continuity.

An other question: How to calculate R2 between variog and variofit
outputs?? Is it possible to extract points of variog?? and so use xvalid.

At the moment, I'm working with geoR library.

Regards,

David
