pvclust_show_signif: The significant branches in a dendrogram, based on a pvclust object

Description

Shows the significant branches in a dendrogram, based on a pvclust object

Usage

pvclust_show_signif(
  dend,
  pvclust_obj,
  signif_type = c("bp", "au"),
  alpha = 0.05,
  signif_value = c(5, 1),
  show_type = c("lwd", "col"),
  ...
)

Value

A dendrogram with updated branches

Arguments

dend

a dendrogram object

pvclust_obj

a pvclust object

signif_type

a character scalar (either "bp" or "au"), indicating which of the two should be used to update the dendrogram.

alpha

a number between 0 to 1, default is .05. Indicates what is the cutoff from which branches will be updated.

signif_value

a 2d vector (deafult: c(5,1)), with the first element tells us what the significant branches will get, and the second element which value the non-significant branches will get.

show_type

a character scalar (either "lwd" or "col"), indicating which parameter of the branches should be updated based on significance.
