This is indeed described in

linked from developer.r-project.org.
with the comment
The purpose of baz is to import some of the exports of foo and bar and
re-export them, using renaming in one case: bar's export g is imported
under the internal name hh, and the internal variable hh is exported
under the name gg. [Renaming seems like a useful option, but it may
turn out to create too many complications and need to be dropped.]
It's been there since 1.7.0 and not yet been dropped. (I would also
suggest checking the R-News article on namespaces, which I have not done.
But checking the developer site is always worthwhile.)
It would be nice to have more end-user documentation on namespaces, and I
have suggested it in the past. A project for you, perhaps?
