swan_connectivity: Impact on connectivity when a node is removed

In NetSwan: Network Strengths and Weaknesses Analysis

Description

Swan_connectivity measures the loss of connectivity when excluding a node.

Usage

swan_connectivity(g)

Arguments

g	The graph to analyze. Graph builds with igraph.

Details

Connectivity loss indices quantify the decrease in the number of relationships between each node when one or several components are removed. Swan_connectivty measures the loss of connectivity when excluding a node.

Value

Numeric vector with the swan_connectivity values of all the vertices.
