It is not that *a* vector of size 443 MB could not be allocated given
your system. However, during your simulation, multiple objects take
up memory, and that 443 MB vector was the final one that was too big
to assign. Depending how your simulation is setup, you might be able
to remove objects that are no longer needed or rewrite it to a less
memory intensive form. I do not know enough about memory+R to offer
any specific advice as to solutions. Hopefully someone else here can
chime in.
Good luck,
Josh
