[R] packagename:::functionname vs. importFrom

[Frank Harrell]

Thanks Hadley, Luke, Martin, and Bill.  Bill captured the essence of my
reasons for needing an unexported function.  Other reasons include
occasional overrides of dispatching rules, and providing parallel versions
of some functions that exist in other packages to make them easier to use in
some sense.  I could ask the package creator to export those functions but
it would not make sense to him to do so.
