| eval.pick {delt} | R Documentation |
Returns a subtree of an evaluation tree. The subtree has a specified number of leafs. The evaluation tree is calculated by "densplit" function. To find out the possible values for the number of leaves we use function "prune".
eval.pick(treeseq, leaf)
treeseq |
an overfitting evaluation tree with information on the possible pruning nodes; output of function "prune" |
leaf |
positive integer; number of leaves in the subtree to be returned |
Returns an evaluation tree, see the documentation of function "eval.cart"
