ext.node: Bind a tip to a terminal branch
In jinyizju/V.PhyloMaker: Make phylogenetic hypotheses for vascular plants, etc.

Description Usage Arguments Value Author(s) Examples

This functions binds a tip to a terminal branch in a phylogeny, and creates a node.

1	ext.node(phylogeny, location.tip, tip.label, node.label = NULL, position = 0.5)

`phylogeny`	The phylogeny.
`location.tip`	The number or label of the tip of the terminal branch.
`tip.label`	The label of the tip to bind.
`node.label`	The label of the node created when binding the tip. The default is NULL.
`position`	The position on the terminal branch to bind the tip, the value must be > 0 and < 1, meaning the proportion of the terminal branch length starts from the tip. The default is 0.5.

phylo

The phylogeny with the tip binded.
