igraph中的颜色特定节点 [英] Colour specific node in igraph

问题描述

我试图为节点6和7着色，无论从对象'd'中选择了什么字母.

I am trying to colour node 6 and 7 regardless of whatever letter is selected from object 'd'.

g <- graph_from_literal(1:2:3:4:5 -- 6:7)
# Rename (sum up all the vertices)
d <- c("a", "b", "c", "d", "e", "f", "g","h", "i", "j")

V(g)$name <- sample(d, 7, replace=TRUE)
colours <- c("red")
V(g)$color <- ifelse(V(g)$name == c('a','e'), "white", colours)

plot.igraph(g, layout=layout_with_dh, vertex.label=V(g)$name, 
vertex.size=35,
vertex.color=V(g)$color, #colors.r
vertex.label.cex=0.7,
)

我尝试了上面的ifelse()，但是它们似乎没有数值.我希望得到一些帮助.

I tried the ifelse() above but they don't seem to take numerical value. I would appreciate some help please.

我想要的是节点6例如白色，例如7绿色，其他节点均为红色.

What I want is that node 6 is e.g. white and 7 is e.g. green and the rest of the other nodes are red.

谢谢！

推荐答案

您可以做到

V(g)$color <- "red" 
V(g)$color[6] <- "white"
V(g)$color[7] <- "green"
