Subject: Re: [R] How do you increase memeory?

memory.limit(size = x)

where x is the desired memory limit in MB.

Hello

Function memory.size() =435109888. How do I
increase it by, say 30%?
Thanks
Meredith

Hi,

Thanks for reading.

I am running  a process in R for microarray data
analysis. RedHat Enterprise Linux 4, dual AMD CPU,
6G memory. However, the R process use only a total
of <200M memory. And the CPU usage is total to ~110%
for two. The program takes at least 2 weeks to run
at the current speed. Is there some way we can
increase the usage of CPUs and memories and speed
up? Any suggestion is appreciated.

Thanks again.

Zhilin
