[R-sig-Geo] gstat or geoR create variogram with sets of bounding boxes

[Javier Moreira]

hi,
im trying to make a variogram that consider a limit made by a bounding box,
but not just one, but dividing the area of the hole set of points in
different subzones (treatments in this case).
I have tried to do so with bounding box in geoR, but i cant do it.
Also, another way its to use anisotropy, but when try to put an alpha
parameter in geostat, doesnt make any change that without it.
bottom line, i have to perform a variogram that includes only the points in
1 direction, or, tell the variogram to limit the surface to a polygon (
several ones)

if any one can help,
thanks
