Summary of Total Object.Size in R Script

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.
