R Interface to C / C++
2 messages · Axel Urbiz, Steve Lianoglou
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

Dear List, I?d like to modify the R rpart package source code to add a new split criterion. I?m familiar with R, but not at all with C or C++. I understand C and C++ are quite different, and I don?t have the time to learn both, so my questions are (i) which one should I learn for the specific task mentioned above? (I understand rpart routines are written in C, but want to check this), (ii) more generally, which one would you recommend me to learn for the purpose of writing interfaces from R to any of these languages? Besides the specific task mentioned above, I?d like to invest my time in learning something that I can use for any later R package building projects. Thanks for any advice.
