| # ランダムグラフを描画し、平均経路長を算出します。 | |
| # p=0.1, 0.3 と変化させ、作図と平均経路長を算出してみましょう | |
| library(igraph) | |
| graph3 <- random.graph.game(50, p=0.05) #頂点は50、線を引く確率は0.05 | |
| plot(graph3) | |
| dev.off() | |
| average.path.length(graph3) | |
| # 第2引数に unconnected = FALSE を加えると、 | |
| # 距離無限大の成分がグラフに含まれる頂点数の値に置き換えられ算出される |
