A "very small script" should fit just fine in an email: what are you
trying to do?
Likely, you are assigning many small variables in some loop. Even if you
have 4GB of RAM available, if R assigns 3.99 GB of it and then then a call
comes in to assign something of size .02, it will tell you it can't
allocate an object of size .02.

[R] improve R memory under linux
Sent by:
r-help-boun...@r-project.org
Dear all,
I am using ubuntu linux 32 with 4 Gb. I am running a very small script
and I always got the same error message: CAN NOT ALLOCATE A VECTOR OF
SIZE 231.8 Mb.
I have reading carefully the instruction in ?Memory. Using the function
gc() I got very low numbers of memory (please sea below). I know that it
has been posted several times at r-help (
http://tolstoy.newcastle.edu.au/R/help/05/06/7565.html#7627qlink2).
However I did not find yet the solution to improve my memory issue in
Linux. Somebody cold please give some instruction how to improve my
memory under linux?
> gc()
used (Mb) gc trigger (Mb) max used (Mb)
Ncells 170934 4.6 350000 9.4 350000 9.4
Vcells 195920 1.5 786432 6.0 781384 6.0
INCREASING THE R MEMORY FOLLOWING THE INSTRUCTION IN ?Memory
I started R with:
R --min-vsize=10M --max-vsize=4G --min-nsize=500k --max-nsize=900M
> gc()
used (Mb) gc trigger (Mb) limit (Mb) max used (Mb)
Ncells 130433 3.5 500000 13.4 25200 500000 13.4
Vcells 81138 0.7 1310720 10.0 NA 499143 3.9
It increased but not so much!
Please, please let me know. I have read all r-help about this matter, but
not solution. Thanks for your attention!
Ricardo
