在 VisNetwork Igraph 中为顶点添加颜色

Question

这是一个更普遍的问题：VisNetwork from IGraph - Can't Implement Cluster Colors to Vertices

我有一个已转换为 visNetwork 的 igraph：

library(visNetwork)
visIgraph(igraph, idToLabel = TRUE, layout = "layout_nicely")%>%
visNodes(size = 10) %>%
visOptions(highlightNearest = TRUE, 
     nodesIdSelection = TRUE)

我有一个颜色列表，这些颜色对应于我要为图形着色的节点：

颜色如下：

c("#80FF00FF" "#FF0000FF" "#FF0000FF" "#00FFFFFF" "#FF0000FF" "#8000FFFF" "#FF0000FF" "#FF0000FF" "#FF0000FF" "#FF0000FF")

如何将这些颜色添加到 visNetwork 的节点？

如果我要这样做，它在正常情节中有效，但在 visNetwork 中无效：

V(igraph)$color <- c("#80FF00FF" "#FF0000FF" "#FF0000FF" "#00FFFFFF" "#FF0000FF" "#8000FFFF" "#FF0000FF" "#FF0000FF" "#FF0000FF" "#FF0000FF")
plot(igraph)

谢谢

Answer 1

您可以将其添加为 igraph 的“组”属性，默认情况下通知节点着色。借鉴您的 other post 中的代码：

col = c("#80FF00FF", "#FF0000FF", "#FF0000FF", "#00FFFFFF",
          "#FF0000FF", "#8000FFFF", "#FF0000FF", "#FF0000FF",
          "#FF0000FF", "#FF0000FF")
i96e <- set.vertex.attribute(i96e, name = "group",value = col)
visIgraph(i96e, idToLabel = TRUE, layout = "layout_nicely")
