There is a mailing list r-help at stat.math.ethz.ch for questions like
this on R. You may want to subscribe to that list and send future
queries about R there.
To answer your current question, I believe Brian Ripley's modreg
library for R has some of the capabilities you wish.
ksmooth Kernel Regression Smoother
loess Local Polynomial Regression Fitting
loess.control Set Parameters for Loess
loess.smooth Simple Smoothing via Loess
plot.ppr Plot Ridge Functions for Projection Pursuit
ppr Projection Pursuit Regression
predict.loess Predict Loess Curve or Surface
predict.smooth.spline Predict from Smoothing Spline Fit
scatter.smooth Scatter Plot with Smooth Curve Fitted by Loess
smooth.spline Fit a Smoothing Spline
supsmu Friedmans's SuperSmoother
Check on any Comprehensive R Archive Network (CRAN) site for
