[R] CPU Usage with R 2.1.0 in Windows

[Greene, Michael]

Hi,

I'm using a fairly simple HP Compaq desktop PC running Windows 2K.  When
running a large process in R, the process "RGUI.exe" will never exceed 50%
of the CPU usage.

The program used to be able to use more of the computer, but does not now.
I don't believe this is a multiple processor machine.

Can anyone give any advice on how to solve the problem?  

Thanks,

Michael Greene
