I have carried out a spatial interpolation (Kriging) using surf.gls()
The contour plot looks very plausible and the image plot is o.k too.
The problem is, hovever, that I need the vectorized isoplethes, as in
Unfortunately, I found no solution to get the internal data from
Is there a possibility to extract contour lines as x-y-polygon from a
grid without hacking plot3d.c?
Thank you in advance!
