It took about 2 hours on the 64 bit windows platform. Now I just need to find my notes from ST733 and remember how to use GSTAT to estimate the parameters....

Tom,

please try to use the variogram function in package gstat; it doesn't (try to) store all pairwise differences, but rather accumulates them for distance intervals.

It will take a while to do this, and there is a chance that you overflow the counter that keeps the number of point pairs for each interval: 304000^2 > 2^32; it is stored as a C long, so may work on a 64 bit architecture. Otherwise, I'd suggest to sample your data set.

I'd be interested to hear whether you succeed (or not).
