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igraph，我已经转换为visNetwork：

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，对应于我想用以下颜色绘制图形的节点：

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？

如果我这样做，它可以在正常的情节中工作，但不能在visNetwork中工作：

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

Answer 1

您可以将其添加为igraph的“group”属性，默认情况下会通知节点着色。借鉴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")

在VisNetwork Igraph中向顶点添加颜色
