带有R的igraph / visNetwork：如何禁用前向链接？

Question

以下代码生成了一个很好的网络图：

library(igraph);library(visNetwork);library(dplyr)

set.seed(123)
nnodes <- 10
nnedges <- 20

nodes <- data.frame(id = 1:nnodes)
edges <- data.frame(from = sample(1:nnodes, nnedges, replace = T),
                    to = sample(1:nnodes, nnedges, replace = T))

visNetwork(nodes, edges) %>%
  visIgraphLayout(layout = "layout_in_circle") %>%
  visNodes(shape="circle") %>% 
  visOptions(highlightNearest = list(enabled = T, hover = T), nodesIdSelection = T)

我的问题是：如何禁用从相邻节点离开的边缘（例如，当选择节点8时，我不希望显示3到9的边缘）。 / p>

编辑：添加了库，thx用于解决问题

使用来自Djack和wici的评论，我实现了以下解决方案：

library(igraph);library(visNetwork);library(dplyr)

set.seed(123)
nnodes <- 10
nnedges <- 20

nodes <- data.frame(id = 1:nnodes, label = 1:nnodes)
edges <- data.frame(from = sample(1:nnodes, nnedges, replace = T),
                    to = sample(1:nnodes, nnedges, replace = T))

visNetwork(nodes, edges) %>% 
  visIgraphLayout(layout = "layout_in_circle") %>% 
  visNodes(shape="circle") %>% 
  visOptions(highlightNearest = list(enabled = T, hover = T, algorithm="hierarchical"),nodesIdSelection = T) %>% 
  visInteraction(hover = T) 

我希望，那就是你要找的东西。
