expand.clade: Expands (or contracts) the tip-spacing of a given clade or clades

Description

The purpose of this function is to compute a custom tip-spacing for users who want to expand or contract the tip-spacing of the descendant taxa from a given node or nodes.

Usage

expand.clade(tree, node, factor=5)
# S3 method for expand.clade
plot(x, ...)

Value

The function returns an object of class "expand.clade" which consists of the (possibly re-ordered) tree and a numerical vector with the calculated tip spacing based on the expansion factor specified by the user. This object can be plotted using the S3 plot method for the object class; or it can be plotted simplying by calling a standard plotting function on the tree & tip spacings.

Arguments

tree

tree an object of class "phylo" or "simmap".

node

node index or vector of node indices.

factor

expansion factor for the tip-spacing of the taxa descended from node or nodes in node.

x

for plot method, an object of class "expand.clade".

...

optional arguments to be passed to plotTree or plotSimmap, depending on the class of x$tree.
