search for: c4.5

I am familiar with the rpart and tree packages for classification and regression trees. However, quite a bit of the research in the transportation community relating to decision trees uses the C4.5 family of algorithms by Quinlan. Are there any plans to make a C4.5 (or a derivative of it) available to R? If not, then I might use the WEKA Java package ( http://www.cs.waikato.ac.nz/ml/weka) that

Greetings, Does anyone know if the C4.5 algorithm is already implemented in R? If yes, please let me know the package. Thanks. -- View this message in context: http://www.nabble.com/C4.5-implementation-in-R-tp23736785p23736785.html Sent from the R help mailing list archive at Nabble.com.

Hello, My question is about the algorithm used behind decision tree package rpart. It is not clear in the help if the algorithm used is ID3 or C4.5. Someone has any idea? Regards.

Hello, exist an implementation of DecisionTree Algorithms C4.5 from Quinlan in R which extract ruleSets for Classification Problems?

Hi All, I am trying to use the C50 package to build classification trees in R. Unfortunately there is not enought documentation around its use. Can anyone explain to me - how to prune the decision trees? Regards, Indrajit [[alternative HTML version deleted]]

Hello, I would like to test some learning algorithms (C5.0, or C4.5) using decision trees or neural network. I didn't find anything in the R documentation for functions to apply on datasets (well, English is not my mother tongue and I have some problems to understand some functions descriptions). Does anybody know where I can find anything about that ? Thank you very much, Thomas

I have installed CentOS 4.5 and 5 on 2 separate machines, and both have default installs of vim-enhanced on each of them. I noticed that I can get syntax highlighting as a regular user, sudo and as root in C4.5. In C5 I only get highlighting as a regular user. I diff'ed my /etc/vimrc files between each install there is no changes and neither root ~ has a .vimrc file. I had put "# vim:
