使用 igraph 将节点度设置为节点属性

Set node degree as a node attribute, using igraph

我想把每个节点的度数作为一个顶点属性,我的代码如下,但是不行,问题出在哪里?

degrees <- igraph::degree(graph)
degree<-sort(degrees, decreasing = TRUE)
dat<- as.data.frame(degree)
#max_degree_nodes<-c(226,194,36) 
V(graph)$name[degrees %in% max_degree_nodes]# tweets that have the most number of ties
vertex_attr(graph, "user_name") <- dat$degree
graph```

这个呢?

set_vertex_attr(
  graph,
  name = "user_name",
  value = degree(graph)
)
