[R] Decision Trees

[Benjamin.STABLER@odot.state.or.us]

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 implements a Java version of C4.5.
Thanks.
