R help - Oct 2005 - Out of memory

Hi,
 
I am using gamm and I run out of memory and R crashes.  I have tried to change
the amount of memory in R using memory.limit as so far the largest it has
allowed
memory.limit(size=3072)
still ahs this problem.
 
If I try to use max I get the following error
> memory.limit(memory.size(max=TRUE))
Error in memory.size(size) : don't be silly!: your machine has a 4Gb address
limit

 
Does anyone have any sugestions on how to get more memory ot R?
 
Thanks,
 
Elizabeth Lawson

Notice that those functions report sizes in bytes, but memory.limit 
takes input in megabytes.  That's the reason for the "don't be
silly"
message.

To get more than 3 GB out of R, you're probably going to have to run a 
64 bit version.  The theoretical limit for 32 bit versions is 4 GB, but 
most OS's reserve 1-2 GB for themselves.
