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?
Yes. See ?"Memory-limits".
help.search("limits") gets you there.
