In response to my request to find functionality for splitting decisions in

Kenton D. Juhlin
Beth Atkinson
Professor Brian D. Ripley

replied that he has written a clone of tree. In both cases the programmer
would need to write C code to alter the split criterion, and have the
ability to compile and link the code.

Rpart can be found at:
