cohesion: Measures of network cohesion or connectedness

In migraph: Multimodal Network Analysis and More

Measures of network cohesion or connectedness

Description

These functions return values or vectors relating to how connected a network is and the number of nodes or edges to remove that would increase fragmentation.

Usage

network_density(.data)

network_components(.data)

network_cohesion(.data)

network_adhesion(.data)

network_diameter(.data)

network_length(.data)

Arguments

.data

An object of a {manynet}-consistent class: matrix (adjacency or incidence) from {base} R edgelist, a data frame from {base} R or tibble from {tibble} igraph, from the {igraph} package network, from the {network} package tbl_graph, from the {tidygraph} package

Functions

• network_density(): Summarises the ratio of ties to the number of possible ties.

• network_components(): Returns number of (strong) components in the network. To get the 'weak' components of a directed graph, please use manynet::to_undirected() first.

• network_cohesion(): Returns the minimum number of nodes to remove from the network needed to increase the number of components.

• network_adhesion(): Returns the minimum number of edges needed to remove from the network to increase the number of components.

• network_diameter(): Returns the maximum path length in the network.

• network_length(): Returns the average path length in the network.
