cohesion {migraph} | R Documentation |
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.
-
network_density()
measures the ratio of ties to the number of possible ties. -
network_components()
measures the number of (strong) components in the network. -
network_cohesion()
measures the minimum number of nodes to remove from the network needed to increase the number of components. -
network_adhesion()
measures the minimum number of ties to remove from the network needed to increase the number of components. -
network_diameter()
measures the maximum path length in the network. -
network_length()
measures the average path length in the network.
Usage
network_density(.data)
