Hello, I am trying to translate a matlab program into R, and I have some problems to find out how to translate the PPVAL function. I know that ppval(pp,xx) returns the value at the points xx of the piecewise polynomial contained in pp( constructed by spline), but I don't know how to do the same thing in R.
Thanks for you help Delphine ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
