Dear R community,
I'm running R 32 bits in a 64-bits machine (with 16Gb of Ram) using a
PAE kernel, as you can see here:
$ uname -a
Linux mymachine 2.6.18-238.el5PAE #1 SMP Sun Dec 19 14:42:44 EST 2010
i686 i686 i386 GNU/Linux
When I try to create a large matrix ( Q.obs <- matrix(NA, nrow=6940,
ncol=9000) ), I got the following error:
> Error: cannot allocate vector of size 238.3 Mb
However, the amount of free memory in my machine seems to be much
larger than this:
system("free")
\ total used free shared buffers cached
Mem: 12466236 6354116 6112120 0 67596 2107556
-/+ buffers/cache: 4178964 8287272
Swap: 12582904 0 12582904
I tried to increase the memory limit available for R by using:
$ R --min-vsize=10M --max-vsize=5000M --min-nsize=500k --max-nsize=5000M
but it didn't work.
Any hint about how can I get R using all the memory available in the machine ?
Thanks in advance,
Mauricio
