R devel - Jul 2008 - allocMatrix limits

I am getting an error "allocMatrix: too many elements specified" when
I
am trying to create large matrix or vector (about 1 billion elements).

How can I find out limits on allocMatrix? Can I increase them?

Thanks,

Vadim.

PS: I am running R on SUSE10 on

?"Memory-limits", and you cannot increase them unless you have a
system
which has larger signed integers.

Thank you for pointing out this.

The problem is in array.c, where allocMatrix check for "if ((double)nrow 
* (double)ncol > INT_MAX)".  But why itn is used and not long int for 
indexing? (max int is 2147483647, max long int is 9223372036854775807)

Thanks,
