[R] Clearing out or reclaiming memory

[gug]

Thanks to everyone who has posted.  These posts have really helped me to
budge forward my understanding of R, as well as giving me a couple of new
areas that I still need to work on.

These (below) won't be news to the people who have posted, but for anyone
who is in my position, here are a couple of expressions that I came across
as a result of following these leads, that are quite useful:

      sapply(ls(), function(x) object.size(get(x)))
-This lists all objects with the memory each is using (I should be honest
and say that, never having used "sapply" before, I don't truly understand
the syntax of this, but it seems to work).

      rm(list=ls())
-This clears out the memory for every object.
