Pre-dating all of these is the variogram function in library(spatial),
since 1994 part of the VR bundle. That's for spatial data, which is how I
read your posting:

I don't think the function in Oswald is, but Variogram in nlme3
can be used for spatial data. However, I don't see how
Variogram can help with `semivariogram model fitting', which
S+SpatialStats certainly can (but is not free).
For spatial data there are also functions in the sgeostat library
available from Statlib.
