Hi
I've been trying to use Darrell's s.surf.krig, could someone email me
a data set and the input parameters (nugget range etc) so I can see
if I've got it working properly. I've tried using my own data but
I can't get it to work satisfactorially, I suspect I'm not using
correct parameters but I'd like to rule out a bug I may have
introduced while compiling it. BTW has anyone done a cokriger
for GRASS
cheers Tom
