sizedsubtree: Find a node subtending to a clade of desired size

In RRphylo: Phylogenetic Ridge Regression Methods for Comparative Studies

Find a node subtending to a clade of desired size

Description

The function sizedsubtree scans a phylogentic tree to randomly find nodes subtending to a subtree of desired minimum size, up to one half of the tree size (number of tips).

Usage

sizedsubtree(tree,Size=NULL,time.limit=10)

Arguments

tree	a phylogenetic tree.
Size	the desired size of the tree subtending to the extracted node. By default, the minimum tree size is set at one tenth of the tree size (i.e. number of tips).
time.limit	specifies a limit to the searching time, a warning message is thrown if the limit is reached.

Details

The argument time.limit sets the searching time. The algorithm stops if that limit is reached, avoiding recursive search when no solution is in fact possible.

Value

A node subtending to a subtree of desired minimum size.
