See ?Memory or the the R for Windows FAQ, which tells you:
"2.7 There seems to be a limit on the memory it uses!
Indeed there is. It is set by the command-line flag --max-mem-size (see
How do I install R for Windows?) and defaults to the smaller of the
amount of physical
RAM in the machine and 1Gb. [...]"

Well, you don't want to allocate 2^30 *Mega*Bytes (see ?memory.limit),
Either use the command line flag --max-mem-size=1500M or within R:

Since your limit was roughly 10^6-times off the right one, you got an
integer overflow internally, I think.
