prune.rpart

prune

Determines a nested sequence of subtrees of the supplied <code>rpart</code> object 
by recursively <code>snipping</code> off the least important splits, based on the 
complexity parameter (<code>cp</code>).

tree

Recursive partitioning for classification,
regression and survival trees.  An implementation of most of the
functionality of the 1984 book by Breiman, Friedman, Olshen and Stone.
