R help - Aug 2011 - going past restrictions on number of elements

Hello R experts,

I'm trying to test R in a shared memory environment in which addressable
memory is aggregrated to about 600G.

However, I get an error of 'too many elements' specified when I try
creating a 45K x 100K matrix.

I tried running R with a --max-nsize=50000000000 option, but got the same
message.

Is there a way to run create such large matrices?

thanks,
Paul Rodriguez

No.  See ?"Memory-limits" (a matrix in R is also a vector).

NB: setting a limit on Ncells (there normally is not one) isn't going 
to help allocation of vectors, is it?
