如何改變節點的顏色？

Question

我正在嘗試根據月份更改節點的顏色。 目前，我已經這樣做了，它根本不簡潔，不適用於大型數據集。 有沒有更好的方法呢？

Data <- read.csv(.....) 

library(igraph)   

MartixData <- as.matrix(Data)

NetworkData <- graph.adjacency(MatrixData, mode="directed", weighted=TRUE)

V(NetworkData)

V(NetworkData)$month <- c("June", "July", "July", "February", "September", "June", "September", "June", "December", "September", "March", "April", "September")

plot(NetworkData, layout=layout.circle, vertex.color=c("yellow", "red", "red", "blue", "pink","yellow", "pink", "yellow", "gray", "pink", "black", "orange", "pink"))

任何幫助將非常感激！

#Results for dput(NetworkData)
structure(list(13, TRUE, 
  c(0, 1, 1, 2, 5, 6, 7, 7, 8, 9, 10, 10, 12, 12, 12, 12, 12), 
  c(11, 4, 12, 0, 12, 1, 6, 12, 1, 4, 9, 12, 1, 5, 7, 10, 11), 
  c(0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16), 
  c(3, 5, 8, 12, 1, 9, 13, 6, 14, 10, 15, 0, 16, 2, 4, 7, 11), 
  c(0, 1, 3, 4, 4, 4, 5, 6, 8, 9, 10, 12, 12, 17), 
  c(0, 1, 4, 4, 4, 6, 7, 8, 9, 9, 10, 11, 13, 17), 
  list(c(1, 0, 1), structure(list(), .Names = character(0)), 
 structure(list(name = c("A", "B", "C", "D", "E", "F", 
    "G", "H", "I", "J", "K", "L", "M"), month = c("June", 
    "July", "July", "February", "September", "June", "September", 
    "June", "December", "September", "March", "April", "September"
    )), .Names = c("name", "month")), structure(list(weight = c(6, 
    6, 7, 6, 7, 6, 6, 7, 7, 7, 6, 7, 7, 7, 7, 7, 7)), .Names = "weight"))), class = "igraph")

使用顏色的查找字典並將其指定為頂點顏色。

myCols <- setNames(c("yellow", "red", "blue", "pink", "gray", "black", "orange"),
                   c("June", "July", "February", "September", "December", "March", "April"))

# assign a colour for vertex
V(NetworkData)$color <- myCols[V(NetworkData)$month]

# then plot, no need to use "vertex.color="
plot(NetworkData, layout = layout.circle)
