branches_attr_by_labels: Change col/lwd/lty of branches matching labels condition

Description

The user supplies a dend, labels, and type of condition (all/any), and TF_values And the function returns a dendrogram with branches col/lwd/lty accordingly

Usage

branches_attr_by_labels(dend, labels, TF_values = c(2, Inf), attr = c("col",
  "lwd", "lty"), type = c("all", "any"), ...)

Arguments

dend

a dendrogram dend

labels

a character vector of labels from the tree

TF_values

a two dimensional vector with the TF_values to use in case a branch fulfills the condition (TRUE) and in the case that it does not (FALSE). Defaults are 2/Inf for col, lwd and lty. (so it will insert the first value, and will not change all the FALSE cases)

attr

a character with one of the following values: col/lwd/lty

type

a character vector of either "all" or "any", indicating which of the branches should be painted: ones that all of their labels belong to the supplied labels, or also ones that even some of their labels are included in the labels vector.

...

ignored.

Value

A dendrogram with modified branches (col/lwd/lty).
