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@b))

this also has

  bunique <- function(b) unique(b)

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

and

  export(bunique)


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
