Hey, R-listers Now I am going to estimate or approximate a surface in 3-D space given a large enough number of (x,y,z) data sets.
So for these 3-D data points, is it possible to get a surface function, like z=f(x,y) to represent this underlying surface? Thanks for your time and point. Fred ______________________________________________ [EMAIL PROTECTED] mailing list http://www.stat.math.ethz.ch/mailman/listinfo/r-help
