[R] poisson regression with robust error variance ('eyestudy

[(Ted Harding)]

I'd like to thank Paul Johnson and Achim Zeileis heartily
for their thorough and accurate responses to my query.

I think that the details og how to use the procedure, and
of its variants, which they have sent to the list should
be definitive -- and very helpfully usable -- for folks
like myself who may in future grope in the archives
concerning this question.

And, just to confirm, it all worked perfectly for me
in the end.

Best wishes,
Ted.
