node.depth {ape} | R Documentation |
These functions return the depths or heights of nodes and tips.
node.depth(phy, method = 1) node.depth.edgelength(phy) node.height(phy, clado.style = FALSE)
phy |
an object of class "phylo". |
method |
an integer value (1 or 2); 1: the node depths are proportional to the number of tips descending from each node, 2: they are evenly spaced. |
clado.style |
a logical value; if |
node.depth
computes the depth of a node depending on the value
of method
(see the option node.depth
in
plot.phylo
). The value of 1 is given to the tips.
node.depth.edgelength
does the same but using branch lengths.
node.height
computes the heights of nodes and tips as plotted
by a phylogram or a cladogram.
A numeric vector indexed with the node numbers of the matrix ‘edge’ of
phy
.
