我无法在 R 中的 igraph 中为我的网络图添加边

Question

我想通过igraph做一个网络图，但是只有节点出现，边/链接没有出现。我的数据来自邻接矩阵。而且我不知道问题出在哪里。有谁知道如何添加边缘？

这是我的脚本：

    library(igraph)

data = structure(list(Adenocalymma_adenophorum = c(NA, 0, 0, 0, 0.003122927,

network <- graph_from_adjacency_matrix (data)


plot(network, edge.arrow.size=.5, vertex.color="gold", vertex.size=15, 
     vertex.frame.color="gray", vertex.label.color="black",

当我运行网络时，出现如下：

IGRAPH 52a911a DN-- 23 0 -- 
+ attr: name (v/c)
+ edges from 52a911a (vertex names)

我的图表： graph

谢谢。

我认为你应该启用参数选项 mode = 和 weighted

graph <- graph_from_adjacency_matrix(data, mode = "directed", weighted = TRUE)

然后 plot(graph) 给你
