Dear all,
I think earlier i didn't clear myself. I ahve a data set of 3 colun and 14000
rows in which first and second column is X and Y coordinates and the third
column is the value of samples of each coordinates points. Now I am trying to
plot semi variogram for the given sample with respect

geoR indeed has some restriction the way is is programed down in the C
code, more or less in the direction Edzer has pointed out.
This can certainly be improved but as a quick solution to run a variogram
computation on 14,000 data or over you should consider raun a function
grom another pac
Dear all,
I think earlier i didn't clear myself. Now i am sending my data file and the
code. My data set is attached with the mail where first and second column is X
and Y coordinates and the column is the value of samples. I hope this time i
am able to communicate.
Thanking you

Right; it computes all pairwise distances in a double loop, but never
stores them.

Dear all,
I am trying to plot semivarigram using the function "variog" but i am getting
following error message "cannot allocate vector of size 757.6 Mb" I suppose my
data set seems large?? it has 14090 samples. I will be thankful if anybody
suggest me the alternative ways to overcome the probl
