R Cannot Allocate Memory Block Of Size 2.0 Gb
This is system-specific, but 32-bit OSes imposes a limit of no more than 4Gb: it is often 3Gb or less.

Each new matrix can’t fit inside the RAM footprint of the old one, so R has to find a *new* bit of contiguous RAM for the newly enlarged matrix. Gc() R Short of reworking R to be more memory efficient, you can buy more RAM, use a package designed to store objects on hard drives rather than RAM (ff, filehash, R.huge, or Not the answer you're looking for?
