Hi, IMHO, if you will be focussing mostly in incorporating C/C++ in your own packages you build, instead of wanting to go into other mixed R/C packages to change them up, I'd go with C++ together with the Rcpp package.
Rcpp makes lots of things easier on your end, that having been said, you should still understand how the mechanics of the .Call interface works and what SEXPs are, and how you manipulate them w/o using Rcpp. HTH, -steve On Tue, Nov 29, 2011 at 7:04 PM, Axel Urbiz <axel.ur...@gmail.com> wrote: > Dear List, > > I’d like to modify the R rpart package source code to add a new split > criterion.
