Compute the Complementary Cumulative Distribution Function (CCDF) of Node Degrees

Source: R/plot_CCDF.R
compute_ccdf.Rd

Computes the CCDF of node degrees for a given igraph object. The CCDF is useful for visualizing degree distributions, particularly on log-log plots, to identify power-law or heavy-tailed behaviors. Internal helper function for plot_CCDF() and compare_networks().

Usage

compute_ccdf(
  graph,
  mode = c("all", "in", "out"),
  remove_singles = FALSE,
  weight_attr = NULL
)

Arguments

graph

An igraph object representing the graph.

mode

Character string indicating which degree type to compute. Options are "all" (default), "in", or "out". Only relevant for directed graphs.

remove_singles

Logical. If TRUE, nodes with degree zero will be removed before computing the degree distribution.

Value

A data frame with two columns:

degree

Integer node degree values.

ccdf

Complementary cumulative distribution values (P(X ≥ x)).
