Dear Mr or Ms genecleaner,
I think you will find that Daniel's suggested explanation, the use of a
normal approximation, fits well with your observation regarding the "exact"
option. So I cannot see why you feel bullied, I found the replies that you
received from the list topical and helpful.
Sin
now that's beautiful! :-)
Many thanks,
David.

Dear R experts,
I have a problem that is a related to the question raised in this earlier post
https://stat.ethz.ch/pipermail/r-help/2007-January/124064.html
My situation is different in that I have only 2 predictors
(coordinates x,y) for local regression but a number of global
("parametric")
I have revised my earlier question to and would be grateful for any
comments!

predictors or a trick to a similar effect?
