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.

library(help=modreg)

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
                           Regression Fit
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
