No. You can get some of the way with
x1 <- gc()[, 1]
copy <- it
x2 <- gc()[, 1]
x1 - x2 - c(5, 6) # correct for variables and function call (fudged)
And from there on things become system dependent. On x386 (Linux and
also Windows IIRC) an Ncell is 20 bytes and a Vcell is 8.
Oddly enough, this doesn't seem to work for functions, and I haven't
got a clue why at the moment:
