Delete a node from the tree

Description

This function deletes a node (and its descendant nodes) from the tree.

Usage

del.node(inode, name, nodematrix)

Arguments

inode	the node to be deleted
name	the species names
nodematrix	the tree node matrix

Details

The species names are those defined in the original tree before deleting the node inode. No need to delete the species name of inode! If inode is an internode, the whole subtree below inode will be deleted.

Value

nodes	the tree node matrix after deleting inode
treestr	the tree string of the tree after deleting inode.
