Calculate given centrality statistic on a network

Usage

get_centrality(network, func.name, package.name = NULL, func.args = NULL)

Arguments

network: The network as an igraph object.
func.name: A character string of the function name used to calculate the desired centrality statistic.
package.name: (Optional) A character string of the name of the package that func.name function is in. If NULL, the function will be called as loaded in the users environment.
func.args: (Optional) A list of additional arguments the func.name function may need beyond the network object. If NULL, no additional arguments will be passed to func.name.

Value

A numeric vector of the centrality statistic as calculated by func.name.

Examples

library(igraph)
data("karate")
