Writing R-extensions

3) The final sentence in the section on `Registering S3 methods' is:

       if the methods are to be found.

  I wonder whether this should actually be:

       Any methods for a generic defined in a package that does not
       use a name space should be exported, and the package defining
       and exporting the generic should be attached to the search path
                         ^^^^^^^
       if the methods are to be found.

  Or is the implication of that sentence that if I have a package
  with a name space which defines a method for a generic defined in
  another package that does not use a name space, then this method
  is only found if my package is attached to the search path and
  mere loading of the namespace is not sufficient?

I think we need to check with the author (Luke, r23430).  If the generic
is not visible there is no dispatch and so this would be irrelevant.
Assuming a typo, your implication is what the svn log entry says and how I
read the text.

Added wording to clarify that S3method registration should only be used if
the generic is defined in a work space.
                            name?
