agree it's wrong. can you point to an example? Martin

Per Hadley:

It's common for packages to be listed in Imports in DESCRIPTION, but not in 
NAMESPACE. In fact, this is what I recommend: list the package in DESCRIPTION 
so that it's installed, then always refer to it explicitly with pkg::fun(). 
Unless there is a strong reason not to, it's better to be explicit. It's a 
little more work to write, but a lot easier to read when you come back to the 
code in the future.

Per R extensions:

If a package only needs a few objects from another package it can use a fully 
qualified variable reference in the code instead of a formal import. A fully 
qualified reference to the function f in package foo is of the form foo::f.
