Re: [R] about memory

How much memory is free when R fails (e.g., what does "top" show while trying to run your clustering)? If there's still a sizeable amount of free memory you may have to look into the system limits, maximum data segment size in particular. Many Linux distros have it set to "unlimited" but default Debian may not. If this turns out to be the problem, please do not, _do not_ raise it to "unlimited," but only to enough for R to work.

I read the help doc and use $R --max-vsize=800M to start the R 2.1.0beta under debian linux.but it still can not get the solution.so is my pc'memory not enough to carry this analysis or my mistake on setting the memory?
