I think Rweka implements the C4.5 (revision 8) algorithm, but it calls it J4.8 (because it's written in Java instead of C, and also the revision number, and is uses an open source licence, i think).
You might want to look at this paper by Schauerhuber, Zeileis & Hornik called 'Benchmarking Open-Source Tree Learners in R/RWeka': http://epub.wu-wien.ac.at/dyn/virlib/wp/eng/mediate/epub-wu-01_bd8.pdf?ID=epub-wu-01_bd8 otherwise, try: http://cran.r-project.org/web/views/MachineLearning.html Hope that helps a little bit, i've been meaning to have a play around with that package myself actually, just need to find the time :D Tony On 27 May, 07:39, Lazy Tiger <lazytig...@gmail.com> wrote: > Greetings, > > Does anyone know if the C4.5 algorithm is already implemented in R?
