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

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 [[alternative HTML version deleted]]

Which is about Windows only, not Linux. (And on Windows, the answer given is on the help page for memory.size. together with a better one.)
