[R] multidimensional splines

[francesca.mancini at ubs.com]

Dear all,

I am looking for a package which performs splining in more than one dimension with polynomials of order>1, exactly as the package "splines" does in 1D.
For the moment I was only able to find the package "polspline", whose function "polymars" performs just piecewise linear splines, so not exactly what I'm looking for.
Do you know of anything else?

Thanks a lot!
