networkD3::saveNetwork(D3_network_LM, "test.html", selfcontained = TRUE)
如此接近,我们有了一个网络。之后,我们通过将多个顶点合并为一个来创建新图。在我们的情况下,属于特定社区的那些顶点。
lesmis <- graph_from_data_frame(df1)
cg <- contract.vertices(lesmis, members)
ay <- as_long_data_frame(cg)
View(ay)
我们得到了新图
from to
1 2
我们可能会再次构建新图,现在这些节点是组,但它们的名称分别是1和2,我的问题是我们如何才能向该新图添加客户端名称。这样,在悬停时,我们不仅可以获取节点(组)的编号,还可以获取属于该新节点(组)的客户端列表。

您的示例代码由于多种原因而无法正常工作(我对其进行了一些编辑以解决一些明显的问题),但是我认为以下实现了您要执行的操作...
library(network)
library(networkD3)
library(igraph)
df <- read.table(header = TRUE,
text = "src target
cllient1 cllient2
cllient1 cllient4
cllient1 cllient6
cllient2 cllient3
cllient4 cllient1
cllient4 cllient3
cllient5 cllient6
cllient6 cllient5")
df_graph <- graph_from_data_frame(df)
wc <- cluster_walktrap(df_graph)
members <- membership(wc)
df_graph_cntrctd <- contract(df_graph, members, vertex.attr.comb = toString)
df_graph_cntrctd_D3 <- igraph_to_networkD3(df_graph_cntrctd)
networkD3::forceNetwork(Links = df_graph_cntrctd_D3$links,
Nodes = df_graph_cntrctd_D3$nodes,
Source = 'source', Target = 'target',
NodeID = 'name', Group = 'name',
opacity = 1, zoom = TRUE)
