Reformulate your problem.
The lme you run with that data attempts to allocate 4GB of memory  
which is a bit too much. Even if you put 8GB in a G5 and run 64-bit  
version of R it's likely to run out of memory or to take forever ...  
Maybe someone will be able to help you to solve your problem in a  
different way if you specify more precisely what you are trying to do  
(including size of the data etc.).
