[Rd] Problem with example(medpolish) in R-devel

[ripley at stats.ox.ac.uk]

That's part of `make check', so you would expect it to run (and it does on
all my systems with the current version in the CVS).  I can only guess
that the snapshot you have has an inconsistency, although I can see no
relevant changes at about that time.

methods(plot) is not going to be very useful in these days of namespaces:
it only shows user-callable methods, and methods are often going to be
unexported but registered. (That's something we need to address in the
documentation, at least.)
