[R] packagename:::functionname vs. importFrom

[Frank Harrell]

In my rms package I use the packagename:::functionname construct in a number
of places.  If I instead use the importFrom declaration in the NAMESPACE
file would that require the package to be available, and does it load the
package when my package loads?  If so I would keep using packagename::: to
avoid up-front loading of other packages that are not always used.

Thanks
Frank
