[R] R died on large data set

[Marcelo Laia]

Hi, I am trying to run a script on R and it died before finish.

I already read the list archives, and memory help pages
(http://tinyurl.com/yaxco6w), but I am unable to solve the issue.

My Debian shows:

marcelo at laia:~$ ulimit
unlimited
marcelo at laia:~$

On system monitor (gnome) I see that R reaches 1.9 Gb, before die.

The R code is:

> ls() ## only todos.norm object are listed
[1] "todos.norm"
> dim(todos.norm)
[1] 9600   15
>
> library("cluster")
> pearson.dist <- as.dist(1-cor(t(todos.norm), method="pearson"))
Died

What I could do to solve my problem?

> sessionInfo() ## after restart R
R version 2.10.1 (2009-12-14)
i486-pc-linux-gnu

locale:
 [1] LC_CTYPE=pt_BR.UTF-8       LC_NUMERIC=C
 [3] LC_TIME=pt_BR.UTF-8        LC_COLLATE=pt_BR.UTF-8

 [9] LC_ADDRESS=C               LC_TELEPHONE=C
