"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.
