Hello, I am relatively new to R (~6 months) so I hate to bother you if this is
not a bug.  I tried a GAM with a poisson family link, and I'm getting an
error
message that I do not understand.  Many apologies if this is user inexperience.
Thanks, BHA.

This is mgcv 0.8.1

Please use r-help rather than r-bugs then...

It's just a warning that gam is using old coding style that is about
to become defunct (specifically gam.fit is using Machine()$double.eps
where the preferred form is .Machine$double.eps). It's harmless but
mgcv 0.8-6 has removed the problem.
