R/Igraph在边列表中显示边权重吗? [英] R/Igraph Display edge weights in an edge list?

问题描述

将图形对象作为边缘列表查看时，有什么方法可以显示边缘权重?

Is there any way to display edge weights when viewing the graph object as an edge list?

我想本着以下的精神做某事:

I want to do something in the spirit of:

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

以查看边缘配对，并在节点旁边列出权重，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.

so as to view the edge pairings with the weights listed alongside the nodes, but that seems not to be allowed. Only way I know how to view the weights is to view the network data as an adjacency matrix. Hoping that's not the only way.

推荐答案

使用帮助页面中pkg:igraph:

Using the example in the help page for function get.edgelist in pkg:igraph:

> 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"
