Centralize a graph according to the degrees of vertices

Description

See centralize for a summary of graph centralization.

Usage

centr_degree(graph, mode = c("all", "out", "in", "total"),
  loops = TRUE, normalized = TRUE)

Arguments

graph	The input graph.
mode	This is the same as the mode argument of degree.
loops	Logical scalar, whether to consider loops edges when calculating the degree.
normalized	Logical scalar. Whether to normalize the graph level centrality score by dividing by the theoretical maximum.

Value

A named list with the following components:

res	The node-level centrality scores.
centralization	The graph level centrality index.
theoretical_max	The maximum theoretical graph level centralization score for a graph with the given number of vertices, using the same parameters. If the normalized argument was TRUE, then the result was divided by this number.

Examples

# A BA graph is quite centralized
g <- sample_pa(1000, m = 4)
centr_degree(g)$centralization
centr_clo(g, mode = "all")$centralization
centr_betw(g, directed = FALSE)$centralization
centr_eigen(g, directed = FALSE)$centralization
