r - 改变 igraph 网络中边的权重

Question

我本以为图形算法会自动获取边缘数据框中的列权重，但它不会如以下代码所示:

nodes <- data.frame(name = c("1", "2", "3"), type = c("a", "b", "b"))
edges <- data.frame(from = c("1", "1"), to = c("2", "3"), weight = c(10000, 50))

net <- graph_from_data_frame(edges, directed=FALSE, vertices=nodes)
V(net)$size <- 2
V(net)$color <- ifelse(V(net)$type == "a", "darkblue", "orange")
V(net)$shape <- ifelse(V(net)$type == "a", "circle", "square")
plot(net)

有没有办法在边缘数据框中使用特定命名的列(例如权重)来设置所描绘边缘的厚度？谢谢!

Answer 1

你可以试试下面的代码

E(net)$width <- edges$weight
plot(net)
