R devel - Mar 2015 - clarification on import/depends for a method

User of the coxme library (mixed effects Cox models) are instructed to use
ranef(),
fixed(), VarCorr(), etc to retrieve bits out of a fitted model; it purposely
uses the same
methods as nlme and/or lmer.

The current behavior is to "depend" on nlme.  If I defined the methods
myself in coxme,
then someone who had both nlme and coxme loaded will suffer from "last
loaded wins", and
the methods for one or the other are not found.  I'm willing to update this
but want to
get it right.  The import(nlme) +  nlme::ranef(fit) solution is not appealing. 
I don't
mind putting :: in my source code, but users of the package should not be forced
into this.

Is the correct current solution (using ranef as an example)
    importFrom(nlme, ranef)
    export(ranef)

then use promptImport() to create a manual page?


If users always had only one of coxme, lmer, or nlme loaded in any given session
then
there are multiple solutions, but occassionally one wants both linear and Cox
mixed effects.

That makes sense to me.
