R help - Dec 2005 - Bivariate Splines in R

Hi..,

    is there a function in R to fit bivariate splines
?
I came across 'polymars' (POLSPLINE) and 'mars' (mda)
packages. Are these the one to use or are there other
specific commands?

Thanks.

Harsh

I'd recommend to use  gam(y ~ s(x1,x2))  from the recommended
package 'mgcv'.

help(gam)  has many examples, some of which using bivariate
splines.

The `gss' package might be worth trying, too.

Cheers,
