[R] Covariace or variogram surface

I'm interested in doing a anisotropy analysis of some spatial data and I
want to do a contour plot of a covariance or variogram surface to
visualize the directions of maximal and minimal anisotropy.

I know how to do a contour plot :-) but how can I obtain the variogram
surface having a geoeas format dataset (X, Y, Z) ?
