[R-sig-Geo] Improve memory in Windows Vista

[Paul Hiemstra]

Hi,

What platform are you using, 64 bit? What kind of dataset? What kind of 
operation do you want to perform on the data? Quite a lot has been said 
on memory usage in R on the "normal" R-help list. Googeling for "R-help 
memory limit" gives tons of information on memory issues. There is bound 
to be something there for you.

cheers,
Paul
