更改一个节点的属性 [英] Change attributes of one node

问题描述

如何从其ID或名称更改颜色标签节点?

How to change a color label node from its id or name?

例如:我想更改标签颜色节点名称="4"或id = 3

Ex: I want to change label color node name="4" or id=3

g9<- graph(c(0,1,0,2,0,3,1,4,1,2,3,4,3,5,4,5,5,2),n=6,dir=FALSE)
V(g9)$name<-c(1:6)
V(g9)$label<-V(g9)$name

推荐答案

V(g9)$color是颜色的数组.

要更改特定节点的颜色，请说2: V(g9)$color[2] ="#343434FF"

To change color of a specific node say 2: V(g9)$color[2] ="#343434FF"

如果每个节点需要不同的颜色，则可以指定rainbow(n)，其中n是节点数，此函数生成颜色数组，然后可以指定:V(g9)$color=rainbow(9)

If you want different color for each node, you can specify rainbow(n) where n is number of nodes and this function generates a array of colors and then you can specify: V(g9)$color=rainbow(9)

还请注意:要获取顶点或节点的列表，您可以获取它们:V(g9) 然后如果您决定更改顶点5的颜色，则可以使用V(g9)$color[which(V(g9)==5)]="#434344" 其中，which(V(g9)==5)匹配顶点或节点5.

Also note: To get a list of vertices or nodes you can get them: V(g9) and then if you decide to change the color of vertex 5, you can use V(g9)$color[which(V(g9)==5)]="#434344" where, which(V(g9)==5) matches to vertex or node 5.
