R help - Aug 2009 - memory limit in R

Hi, all, I'm doing a discrete choice model in R and kept getting this error:
Error: cannot allocate vector of size 198.6 Mb.

Does this mean the memory limit in R has been reached?

[1] 1535

My laptop has a 4G memory with Windows Vista (32 bit). I increased the
memory limit to 2500 M. But still getting the same error message. Any one
can give me some suggestions? Thanks.

See ?Memory and find that more than 2047 Mb is not easily possible on 
your 32-bit  (and might not even be sufficient for your problem).

The size of my .Rdata workspace is about 9.2 M and the data I'm using is the
only one object in this workspace. Is it a large one?
Thanks.
