about memory
root at 2[ronggui]# ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited file size (blocks, -f) unlimited max locked memory (kbytes, -l) unlimited max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) unlimited virtual memory (kbytes, -v) unlimited so it seems the data segment size is not limited. and it is still free mem(1000k or so),and swap(100000k or so),and the error is(i translate it from chinese into english,maybe not exactly ,but i think the meanings are right): error:can not allocate the vector size of 390585kb.

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. hth, jon b On Wed, 30 Mar 2005 18:36:37 +0800 ronggui <0034058 at fudan.edu.cn> wrote:
here is my system memory:
ronggui at 0[ronggui]$ free
total used free shared buffers cached
Mem: 256728 79440 177288 0 2296 36136
-/+ buffers/cache: 41008 215720
Swap: 481908 60524 421384
and i want to cluster my data using hclust.my data has 3 variables and 10000 cases.but it fails and saying have not enough memory for the vector size. 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?
thank you.
