R help - May 2008 - Insufficient memory

Dear Sir/Madam,

I have only started using a R-written script for modeling the distribution of
disease vector species. Part of the script is to make a large GIS grid for use
with GIS software, but it seems I have a memory problem. I get the following
message:

Reached total allocation of 1535Mb: see help(memory.size)

My hard disk has more than 100 gigabytes available, I just have to increase the
allocated memory -  sofar unsuccesful. I've used the code:
> memory.limit(4094)  which returns: NULL. 
When I then use the code: > memory.limit(size = NA) it returns: [1] 4094. But
then when I run the code to produce the large grid, I still get the same error
message as above.
How do I go about to increase the memory to the maximum?

Your help is much appreciated.

Regards

Roy Williams

Tell your unstated OS that you want more of the address space?  See the 
rw-FAQ.
