[R] what are the limits on R array sizes?

[Mike Miller]

I have some computers with a massive amount of memory, and I have some 
jobs that could use very large matrix sizes.  Can R handle matrices of 
larger than 2GB?  If I were to create a matrix of 1,000,000 x 1,000, it 
would use about 8GB.  Can R work with an array of that size if I have 
compiled R on an IA64 Linux system with 15GB of RAM?
