karate_club_graph

karate_club_graph()

karate_club_graph constructs a karate club graph.

This function uses the Zachary’s karate club dataset to create a graph object. Nodes represent members of the club, and edges represent relationships between them. Node properties indicate the club to which each member belongs.

Background:

These are data collected from the members of a university karate club by Wayne Zachary. The ZACHE matrix represents the presence or absence of ties among the members of the club; the ZACHC matrix indicates the relative strength of the associations (number of situations in and outside the club in which interactions occurred). Zachary (1977) used these data and an information flow model of network conflict resolution to explain the split-up of this group following disputes among the members.

Returns:

A Graph object representing the karate club network.
