[R] Memory issues..

[Rodrigo Abt]

Hi dear R-listers, I'm trying to fit a 3-level model using lme in R. My
sample size is about 2965 and 3 factors:

year (5 levels), ssize (4 levels), condition (2 levels).

When I issue the following command:

>
lme(var~year*ssize*condition,random=~ssize+condition|subject,data=smp,method
="ML")

I got the following error:

Error in logLik.lmeStructInt(lmeSt, lmePars) :
        Calloc could not allocate (65230 of 8) memory
In addition: Warning message:
Reached total allocation of 120Mb: see help(memory.size)

I'm currently using a Win2000 machine with 128Mb RAM and a 1.2 Gb processor.
My version of R is 1.7.1.

Thanks in advance,
