plot_dendrogram {igraph}R Documentation

Community structure dendrogram plots

Description

Plot a hierarchical community structure as a dendrogram.

Usage

plot_dendrogram(x, mode = igraph_opt("dend.plot.type"), ...)

## S3 method for class 'communities'
plot_dendrogram(
  x,
  mode = igraph_opt("dend.plot.type"),
  ...,
  use.modularity = FALSE,
  palette = categorical_pal(8)
)

Arguments

x

An object containing the community structure of a graph. See communities for details.

mode

Which dendrogram plotting function to use. See details below.

...

Additional arguments to supply to the dendrogram plotting function.

use.modularity

Logical scalar, whether to use the modularity values to define the height of the branches.

palette

The color palette to use for colored plots.

Details

plot_dendrogram supports three different plotting functions, selected via the mode argument. By default the plotting function is taken from the dend.plot.type igraph option, and it has for possible values:

The different plotting functions take different sets of arguments. When using plot.phylo (mode="phylo"), we have the following syntax:

    plot_dendrogram(x, mode="phylo", colbar = palette(),
            edge.color = NULL, use.edge.length = FALSE, \dots)

The extra arguments not documented above:

The syntax for plot.hclust (mode="hclust"):

    plot_dendrogram(x, mode="hclust", rect = 0, colbar = palette(),
            hang = 0.01, ann = FALSE, main = "", sub = "", xlab = "",
            ylab = "", \dots)

The extra arguments not documented above:

The syntax for plot.dendrogram (mode="dendrogram"):

    plot_dendrogram(x, \dots)

The extra arguments are simply passed to as.dendrogram.

Value

Returns whatever the return value was from the plotting function, plot.phylo, plot.dendrogram or plot.hclust.
