You are trying to create an object with 1G elements.  Given that these
are integers, this will require about 4GB of space.  If you are
running on a 32-bit system, which has a total phyical limit of 2-3GB
depending on what options you are running (at least on Windows), then
you have exceeded the limits.  It is a good idea to limit your largest
object to about 25% of physical memory in case copies have to be made
during some of the analysis.
