Following WRE 1.5.6 (Namespaces with S4 classes and methods), you should
have "Depends: methods" in your DESCRIPTION, and "import(methods)" or a
more selective "importFrom(methods, ...)" directive in your NAMESPACE.
Then you would usually use the NAMESPACE directive
importMethodsFrom(package,
Thanks for pointing to the bug.
Now I am finding I cannot use the 'as' definitions from 'raster' without
loading the package. Do I need an @import directive that specifies the
definitions in the 'raster' package? My understanding is that the 'setAs'
function generates a 'coerce,...' signature but
Yes, indeed, it is confusing. You don't need to file a new bug report, though.
There is one already:

Please feel free to comment there. This thread could serve as another
confirmation. :-)

to the Imports: statement in your DESCRIPTION file and see if that
helps. (Maybe I should file a bug report about that error message - it
confuses me every time.)
