在R中运行群集\u边缘\u中间值时发出警告

我尝试使用R中的IGRAPHE软件包基于边缘介数进行社区结构检测。当边缘加权时，出现一些警告：

警告信息：

1: In cluster_edge_betweenness(g) :
  At community.c:460 :Membership vector will be selected based on the lowest modularity score.
2: In cluster_edge_betweenness(g) :
  At community.c:467 :Modularity calculation with weighted edge betweenness community detection might not make sense -- modularity treats edge weights as similarities while edge betwenness treats them as distances

当边缘未加权时，它在没有任何警告的情况下正常工作

以下是生成警告的代码：

library(igraph)
g <- make_full_graph(10) %du% make_full_graph(10)
g <- add_edges(g, c(1,11))
E(g)$weight <- seq(1,91)
eb <- cluster_edge_betweenness(g)
