I was *just* going to post this same thing myself! My environment is a 400
MHz P III running Windows 2000 Professional, and I get the error at 127 MB on
my 128 MB machine :-). And I get the same thing on my 192 MB machine at home.
I am doing a "read.csv" on a 15 MB "CSV" file. What's even more interesting is
that this consumes so much memory that "q()" stops working!! I have to kill it
with the Task Manager. I haven't checked to see how big my pagefile is yet,
but it's obviously checking how much RAM is installed and hitting some kind of
wall there. I have some bigger Linux boxes available that I can try this
one on, so I may be able to get it to completion without waiting for the
latest R or trimming my data set. I can't do much about the rows, but it's
easy for me to drop unneeded columns; the raw data is coming from Microsoft
Access.
