Instruções do exercício

  • Use the function edge.betweenness.community() on the graph object g to create the community igraph object gc.
  • Calculate the size and number of communities by using the function sizes on the community igraph object.
  • Plot each community plot next to each other using par(). The first plot should include the community object kc from the previous exercise. The second plot should include the community object gc.
