Hi, I have a very non-specific question about the number of sample points that
can be used 
for developing experimental variograms and kriging in R/gstat/etc. Does anyone
have experience 
using a very large number of data points in the kriging processes with R?  It
has been a few 
years since my last spatial stats course but I recall that I was limited in the
number of data 
points that R could handle.  I have a regional archaeological dataset with many
data points.
My sub-regions that I would like to use for kriging can contain 8,000-10,000
data points.  Many 
of these are zero values (not no data).  Am I going to have sample my sample if
I want to 
generate experimental variograms in R? Thanks in advance for any ideas, 
Greg Luna
