R: Correlation matrix between a list of trees.

cor.dendlist {dendextend} | R Documentation

## 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"), ...)

### 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.

### Value

A correlation matrix between the different trees

    #    cutree(dend1)
    cors <- cor.dendlist(dendlist(d1 = dend1, d2 = dend2, d3 = dend3, d4 = dend4))
