[R] GAMs under R?

Linked from my web page (and on the RSS site) there's an R package
(mgcv) for fitting and smoothing parameter estimation (by GCV) for models
with multiple penalties. I wrote it to deal with various non-linear
problems, but it lets you set up GAMs using penalized regression splines -
and the package includes code for doing this. If this is any use to you,
you'd need to add in the `generalized' bit of GAMs yourself, but that's
pretty trivial, given the code that's there (it's on my `to do' list).
The smoothing parameter selection method is a generalization of Gu and
Wahba's multiple gcv method for spline models to problems with less
structure.
