That is certainly true because I have seen differences due to the
sharing of values. I also look at what 'gc()' shows at the memory
being used. Does this provide a reasonable estimate of the total
space being used?
Yes, but not just by your workspace, also all the loaded packages.

Here is a function I use to see how big the objects in my workspace are:
Be careful with the caveats spelled out in ?object.size. Especially for
character data such summations can be way off.

Dear all,
Is there a way we can find the total object.size of
all the objects in our R script?
The reason we want to do this because we want to know
how much memory does our R script require overall.
Rprofmem(), doesn't seem to do it.
and Unix 'top' command is dynamic and
it doesn't give the exact byte size.
