r - 顶点标签从 id 更改为 igraph 中的另一列

Question

我正在创建一个将 id 作为顶点名称的图。但是我想将顶点标签更改为另一个列值。我怎样才能做到这一点？

df1 中的列是 ID、名称，我希望顶点标签是名称

我的代码：

df1:
ID  NAME
1   Ada
2   Cora
3   Louise
            
df2:
SOURCE  TARGET  TYPE       ID  WEIGHT
1       2       DIRECTED   2   2   
1       3       DIRECTED   1   2
2       1       DIRECTED   3   1



  g = graph.data.frame(d = df2, directed = TRUE, vertices = df1);    
    V(g)$size<-degree(g)
        plot(g,                
             layout=layout.circle, main="circle", 
             vertex.label.dist=0.4,          
             vertex.label=V(g)$id,      
             vertex.label.cex=1, edge.arrow.size=0.

谢谢

你可以试试

g %>%
    set_vertex_attr(
        name = "name",
        value = V(.)$NAME
    )

这使

IGRAPH 19e91db DN-- 3 3 --
+ attr: name (v/c), NAME (v/c), TYPE (e/c), ID (e/n), WEIGHT (e/n)
+ edges from 19e91db (vertex names):
[1] Ada ->Cora   Ada ->Louise Cora->Ada
