It might help if you specify your hardware, OS (presumably Windows?)
and version, and your R version. Also possibly how large your vectors
are and what other processes you have running.

Other than that, I have no clue, of course.

However, sometimes when I try to do this my computer will freeze and I am unable to stop or escape the process, requiring me to shutdown R via the task manager. I was wondering if anybody else experiences this and, if so, why this might be happening.
