Hi Spyros,

I suggest that you borrow / buy the book that was written by the author of
that package, and study it. It's "Generalized Additive Models: An
Introduction with R". There's a lot of stuff going on in GAM fitting
that
it would be worth paying close attention to.

I hope that this helps,

Andrew
