vulnerability: Calculate graph vulnerability

Description

This function calculates the vulnerability of the vertices of a graph. Here, vulnerability is considered to be the proportional drop in global efficiency when a given node is removed from the graph. The vulnerability of the graph is considered the maximum across all vertices.

Usage

vulnerability(g, use.parallel = TRUE, weighted = FALSE)

Arguments

g
An igraph graph object
use.parallel
Logical indicating whether or not to use foreach (default: TRUE)
weighted
Logical indicating whether weighted efficiency should be calculated (default: FALSE)

Value

A numeric vector of length equal to the vertex count of g
