the source of your problem.

It has this heading:

If your system is Windows, you can also try to increase the memory available
for one application, in order to avoid the problem.
Do a search for "3GB switch"

Dear Mauricio,
what I do not understand at all is the message:

Have you tried to allocate a big matrix in between, whith
the R - statement not being shown in the output? Probably
not. If not, your local R version is buggy for sure. The test shows
Dear Hugo,
I tried your memory test program (without further modifications) just
after the gc() command:
print(gc())
print(gcinfo(TRUE))
system("/mypath/memorytest.out")
and the result that I got was:
Number of simulations read from ' Particles.txt ' : 9000

Hello Mauricio,
No, your gcc version is unduly puristic here. The traditional return
type of the main function in "C" should be "int", and i
Thank you very much Hugo for your answer.
Yesterday I was out of my office and I couldn't test the advise you
gave me. Today I'll do it.
I have never used C, so I have to ask.
For creating an executable file with your code, I copied and pasted
the text into a text file, and then tried from the

I tried your matrix allocation on Gentoo-hardened 32 and
64 bit systems. Both work ok, using R-2.11.1 and R-2.12.2 respectively,
and both use a recent 2.6.36 kernel revision.
This is from the 32 bit system with 512 MB physical memory:

Following the advice a colleague, I put the gc() and gcinfo(TRUE)
commands just before the line I got the problem, and their output
were:

Thanks for your answer Martin, but -unfortunately- the decision about
installing a 32 bits OS in the 64 bits machine, was taken by the IT
guys of my work and not by me.
By the way, due to strong limitations about software installation in
my work place, this problem didn't happen in Ubuntu, but in

I would suggest two things here:
check on the size of other object you may have stored in memory, and get rid
of what you don't need.
? ls
? rm
also, consider running garbage collection to help free up memory in R
gc()
I hope this helps!

Dear R Users,
I was running some data analysis scripts and ran into this error:

Doing a "memory.size(max=TRUE)" will give me:

The current situation is:
I'm working on a Windows Vista 32bit lap
Also,each data.frame of the 1500 working as data sources floating in
the global environment is of a size ranging from 2000x36 to 9000x36
Please help...! THANKS!!!
