To whom it may concern,

I seem to be encountering RAM problems using R.  I am currently running R 
2.2.0 in Windows XP version 2002.  My computer has 4 GB of RAM.  The 
problem I am encountering is that R does not seem to allow me to obtain 
more than 1.5GB of  RAM as I construct various matrices.

I have already pre-allocated 3.5 GB of RAM as in the command line I entered 
under "Target": "C:\Program Files\R\R-2.2.0\bin\Rgui.exe" 
--max-mem-size=3500Mb.

However, R still seems to be blocked at 1.5GB.  Once I have more than about 
1.5 GB of RAM allocated to the various objects in memory, I get an error 
that R cannot allocate the matrix.

Is there an internal RAM limit for R?  Are there any work-arounds?

Thank you very much,

JP
