Plot weighted centrality indices for a catgraph

Source: R/centrality.R
plot_centrality.Rd

Produces a ranked horizontal bar chart of one or all centrality measures from a catgraph object. When a single measure is selected the chart shows bars ranked by that measure. When measure = "all", a faceted or overlaid comparison chart is produced.

Usage

plot_centrality(
  x,
  measure = "strength",
  normalize = TRUE,
  title = NULL,
  color = "#7F77DD",
  engine = c("ggplot2", "base")
)

Arguments

x

A catgraph object.

measure

Character. One of "strength", "w_betweenness", "w_closeness", "w_eigenvector", "w_pagerank", or "all". Default "strength".

normalize

Logical. Passed to node_centrality. Default TRUE.

title

Character. Plot title. Default NULL.

color

Character. Bar fill colour. Default "#7F77DD" (purple-400).

engine

Character. "ggplot2" (default) or "base".

Value

For engine = "ggplot2": a ggplot object. For engine = "base": NULL, invisibly.

Examples

df <- expand_table(Titanic)
cg <- catgraph(df)
plot_centrality(cg)

plot_centrality(cg, measure = "w_betweenness")

# plot_centrality(cg, measure = "all")  # requires ggplot2
