object size versus saved size?

Posting under new subject.

I?ve a question on saving a earth object to disk.
Say m is the model then
print(object.size(m), units=?Mb?)
163.8 Mb
and save it off
save(m, ?tmp.rda?)
and ?tmp.rda? is roughly 171Mb file.

I would like this to be much smaller.
So I try
m$bx<-NULL
then
print(object.size(m), units=?Mb?)
14.9 Mb Great!
however when I save it off
save(m, ?tmp.rda?)
and ?tmp.rda? is roughly 171Mb file ? the same size.

I do not care about the size of the file per se, I care about loading a
smaller object at a future date.
