"CART" is a trademarked statistical procedure owned by Salford Systems
of San Diego, CA.  If you're looking for an R-package that implements
the procedures described in the Breiman, Friedman, Olshen, and Stone
book entitled "Classification and Regression Trees", the closest you
can come to the original algorithm is the R-package called "rpart", by
Therneau and Atkinson.  If you combine that with Andy Liaw's
"randomForest", you have a pretty potent set of tools.  If you really
want "CART", you need to contact Salford Systems for their
implementation and pay their very expensive licensing fees.
