Using NAMESPACE, I was able to hide my globals behind a

WHY do you want to ``prevent users from seeing [your] globals''?
The whole point of R (well, maybe not the whole point, but a major
point) is to be adaptable. If something doesn't work the way a user
wants, then the user can change things. When the inner workings
are hidden so deeply that the user can't see what to change, this
becomes effectively impossible, and the user might as well go and
use SAS.
I exaggerate but slightly.
Nevertheless, this syndrome of hiding things and making them
effectively
inaccessible --- which seems to have become an obsession with some
of the
R community, particularly many of the senior members --- bugs the
living
Drambuie out of me.
