Error in vector("double", length) : vector size specified is too large

Turns out I was wrong re: # of rows...it's 304,000


Same problem. Version is 2.1.1, hardware is Dual Xeon 3.6 4 GB RAM, XP Pro
64 Bit. Can reproduce the problem with 64Bit R 2.1.1 running on Fedora 4,
same hardware.

Well you could start by removing large objects that you aren't using (e.g.
'data1') and seeing if that helps. 

There may be other suggestions but you haven't told us what platform you're
working on, as the posting guide requests:
