All,

I am working with a large data set (~ 450,000 rows by 34 columns) I am
trying to fit a regression model (I have tried to use several procedures psm
(Design package) lm, glm). However whenever I try to fit the model I get the
following error:


Error: cannot allocate vector of size 1.1 Gb

Here are the specs of the machine and version of R I am using

Windows Server 2003 R2 Enterprise x64 Service Pack 2

Intel Pentium D 3.00 Ghz
3.93 GB Ram

R 2.6.0

when I type the command

memory.limit()
I get:
3583.875

I assume that means that I have about 3.5 GB at my disposal  so I am
confused why I can't allocate a vector of 1.1 GB. Any suggestions on what to
do.

Best,

Spencer
