Hello everybody, I'm a new user of R and I'm working right now with the ACE function from the acepack library. I Have a question: Is there a way to predict new responses using ACE? What I mean is doing something similar to the following code that uses PPR (Projection Pursuit Regression): library(MASS) x <- runif(20, 0, 1) xnew <- runif(2000, 0, 1) y <- sin(x) a <- ppr(x, y, 2) ynew <- predict(ppr, xnew) Any help would be much appretiated, Thanks in advance, Luis Pineda

Look at the areg.boot function in the Hmisc package, and its associated predict method.
