Dear List,
Id like to modify the R rpart package source code to add a new split
criterion. Im familiar with R, but not at all with C or C++.
I understand C and C++ are quite different, and I dont 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, Id like to
invest my time in learning something that I can use for any later R package
building projects.
Thanks for any advice.
Regards,
Axel.
