spline with multiple predictor vars?

There are thin plate regression splines in mgcv and thin plate splines and
tensor product splines in gss that will probably do what you want.

See examples in mgcv helpfile ?gam for a couple of examples.

Hi, is there a way in R to generate a polynomial spline with multiple predictor
variables? I have one response and two predictors and I'm trying to fit a
spline model for this...

gam() and friends comes close.  Not literally a cubic B spline,
but the same effect.  "Generalized Additive Models" a la Hastie
and Tibshirani.

Thanks for all the suggestions.. I will investigate thin plate regression 
splines, gam, mars... would the best references for these be the ones 
mentioned in the help for these?

Thanks,
