Measures of network fragmentation

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

• net_by_cohesion() measures the minimum number of nodes to remove from the network needed to increase the number of components.

• net_by_toughness() measures the number of nodes that would need to be removed from a network to increase its number of components.

• net_by_adhesion() measures the minimum number of ties to remove from the network needed to increase the number of components.

• net_by_strength() measures the number of ties that would need to be removed from a network to increase its number of components.

Arguments

.data

A network object of class mnet, igraph, tbl_graph, network, or similar. For more information on the standard coercion possible, see manynet::as_tidygraph().

Value

A network_measure numeric score.
