'methods' continues to have seemingly different treatment.
If you try to use importFrom to import a single function (in this case
'hasArg') from methods, you receive an ERROR from R CMD check
Namespace dependency not required : 'methods'
That message usually means that you didn't list 'methods' in the Imports
clause in DESCRIPTION.
Is there a better way of formulating the message?
Packages used in the NAMESPACE file must also be in the Imports: or
Depends: field of the DESCRIPTION file; missing packages : 'methods'
Package(s) not present in Imports: or Depends: of DESCRIPTION :
'methods'
... ?

but without the importFrom, you see a number of NOTE's
no visible global function definition for 'hasArg'
I don't want to import all of 'methods', as I only need one function.
What am I doing wrong?

Brian
