R/Igraph 在边列表中显示边权重？

Question

当将图形对象作为边列表查看时，有什么方法可以显示边权重吗？

我想做一些本着以下精神的事情:

get.edgelist(graph, attr='weight')

以便查看边缘配对与节点旁边列出的权重，但这似乎是不允许的。我知道如何查看权重的唯一方法是将网络数据视为邻接矩阵。希望这不是唯一的方法。

Answer 1

使用 pkg:igraph 中函数 get.edgelist 的帮助页面中的示例:

> cbind( get.edgelist(g) , round( E(g)$weight, 3 ))
      [,1] [,2] [,3]   
 [1,] "a"  "b"  "0.342"
 [2,] "b"  "d"  "0.181"
 [3,] "b"  "e"  "0.403"
 [4,] "b"  "f"  "0.841"
 [5,] "d"  "f"  "0.997"
 [6,] "e"  "g"  "0.029"
 [7,] "a"  "h"  "0.17" 
 [8,] "b"  "j"  "0.69" 
 [9,] "g"  "j"  "0.422"
