问题描述

visNetwork图中边的箭头颜色有可能与边的颜色不同吗？

 library(visNetwork)
    nodes <- data.frame(id = 1:4,label=1:4)
    edges <- data.frame(from = c(1,2,3,4),to = c(2,4,1))
    
    
    visNetwork(nodes,edges,width = "100%") %>%
 
      visNodes(shape = "square",color = list(background = "lightblue",border = "darkblue",highlight = "yellow"),shadow = list(enabled = TRUE,size = 10)) %>%
visEdges(shadow = TRUE,arrows =list(to = list(enabled = TRUE,scaleFactor = 0.5)),color = list(color = "cyan",highlight="cyan"))%>%
      visLayout(randomSeed = 12) # to have always the same network
