I could be wrong, but I think you did not provide information on your
platform. Assuming it is Win32, it is an FAQ, please see:

You will hit memory limits rather quickly if you want to allocate not
only one of your 3.6GB vectors - and this is neither the fault of R nor
Although I don't have a background in Computer Science, I think the
physical limit to address memory on a 32bit system is 4GB.
I hope this helps?
(And I hope I did not claim anything wrong about 32bit systems)
