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
