具有相同颜色(特征)的R igraph簇节点

Question

# example data
library(igraph)
links <- cbind.data.frame(from = rep("A", 6),
                      to = LETTERS[1:6],
                      weight = rep((1:3), each =2))

nodes <- nodes <- cbind.data.frame(id = LETTERS[1:6],
                               feature = rep((1:3), each =2))

net <- graph_from_data_frame(d = links, vertices = nodes, directed = T) 
V(net)$color <- V(net)$feature
plot(net, vertex.size=30, edge.arrow.size = 0)

这是我得到的:

我想要的是将相同颜色的节点聚集在一起，类似于下图所示。我该怎么做？

Answer 1

也许 plot 中的选项 mark.groups 会有所帮助

plot(net,mark.groups = split(V(net)$name,V(net)$color))
