PkgA promotes 'unique' to a generic and exports that

   DESCRIPTION:
   Imports: methods

   R/f.R:
   setGeneric("unique")

   NAMESPACE:
   export(unique)

and PkgB creates and exports a method on unique

   DESCRIPTION
   Imports: methods, PkgA

   R/f.R:
   setClass("B", representation(b="numeric"))
   setMethod(unique, "B",
             function(x, incomparables=FALSE, ...) unique(x at b))

   NAMESPACE:
   importFrom(PkgA, unique)
   exportClasses(B)
   exportMethods(unique)

There is a man/ page for each package, but no other documentation. Yet

    R CMD check PkgA_1.0.tar.gz

says

* checking for missing documentation entries ... OK
* checking for code/documentation mismatches ... OK

and for Pkg B we only get

* checking for missing documentation entries ... WARNING
Undocumented code objects:
   ‘bunique’
All user-level objects in a package should have documentation entries.
See the chapter 'Writing R documentation files' in the 'Writing R
Extensions' manual.
* checking for code/documentation mismatches ... OK
