eval.pick: Returns a subtree of an evaluation tree

Description

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".

Usage

eval.pick(treeseq, leaf)

Arguments

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

Value
