add_islands_graph {DiagrammeR} | R Documentation |
To an existing graph object, add several Erdos-Renyi random graphs (the islands) using a common set of parameters, connected together by a fixed number of edges.
add_islands_graph(graph, n_islands, island_size, p, edges_between, type = NULL, label = TRUE, rel = NULL, node_aes = NULL, edge_aes = NULL, node_data = NULL, edge_data = NULL, set_seed = NULL)
