Short answer: `Yes'. Slightly longer answer: `rapart classification tree' is not something Google knows about, and bagging is not to do with `grow a tree'. More informative answer: Bagging is a method to combine ensembles of classification trees, and *rpart* is a package in R which does grow and prune classification trees. CART is the trademark of a commercial program to grow and prune classification trees. Put `bagging Breiman' into Google to help you with the concept of bagging, and then look at package ipred.
