I am having trouble with this error when calculating a density on a
point pattern dataset with 34480 points.
My script exit when calculating
z-density(mypattern, 3000, dimyx=3000)
The machine the script it's running on it's a debian/amd64 OS with
16Gb RAM, I have set to unlimited the memory limits (the output of
ulimit -a follows)
Any ideas?
Try:
?memory.limit
?gc
and read 'Circle 2' of the R_inferno
(www.burns-stat.com/pages/Tutor/R_inferno.pdf)
IHTH,
Mauricio
Circle 2 is interesting but it's not my case, I do not costruct object
that way and fetch data from a postgres/postgis database.
Putting in the code lines such as
cat('point 1 mem', memory.size(), memory.size(max=TRUE), 'nn')
doesn't help because those commands are windows specific and I work on linux.
Here follows a link to my script and RData, lines commented are not
needed because objects are in the RData
http://cen.isprambiente.it/~rmorelli/R/
I've just purged unusued objects from RData.

Cheers, Roman I can upload my .RData (~45Mb) on a server and the script if you're willing to try. In the meanwhile I am doing some test with my owin taken from the maps dataset, I guess the one I am using is too much detailed. -r ___ R-sig-Geo mailing list R-sig-Geo@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-geo
