Allocation problem

Hi,

I have a problem when using R1.7.0. I have a very large dataset, but I 
also have access to 24GB RAM on a super-computer. Nevertheless, when 
using the "lme"-function  I get the error message

Error: cannot allocate vector of size 224295 Kb

As I understand it, the default is that there is no memory-limit in R 
other than machine resources, but somehow R does not get acces to the 
24GB of RAM I have available.

Does anyone have a tip? I have tried
