cor.dendlist: Correlation matrix between a list of trees.

Description

A correlation matrix between a list of trees.

Assumes the labels in the two trees fully match. If they do not please first use intersect_trees to have them matched.

Usage

cor.dendlist(
  dend,
  method = c("cophenetic", "baker", "common_nodes", "FM_index"),
  ...
)

Value

A correlation matrix between the different trees

Arguments

dend

a dendlist of trees

method

a character string indicating which correlation coefficient is to be computed. One of "cophenetic" (default), "baker", "common_nodes", or "FM_index". It can be abbreviated.

...

passed to cor functions.
