[R] readAsciiGrid memory issues

[Alexander.Herr at csiro.au]

Hi List,

I am unable to read in a 7.8Gb ascii grid using readAsciiGrid {maptools} - R runs out of memory. I have 4Gb ram and 4Gb swap, so things are getting tight.

I am wondering if anyone has alternative options (preferably with example) that enable to read in large grids, do some calculations and save a new grid?

I am running linux 64bit on opensuse11 and R 2.8.0

Thanx
Herry
