Hi, I have a dataset with two independent variables (x, y) and a response variable (z). I was hoping to generate a response surface by plotting x, y, z on a three dimensional plot. I can plot the data with rgl.points(x, y, z). I understand I may not have enough data to generate a surface. Is there a way to smooth out the data points to generate a surface? Thanks a lot.
Jun =========================== An example: x<-runif(20) y<-runif(20) z<-runif(20) library(rgl) rgl.points(x,y,z) [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
