我有一个简单的sankey图,使用networkD3一个闪亮的应用程序内的包生成.如何source和/或target节点排序？

正如您在MWE中看到的那样,默认情况下,源节点(A,B,C,D,E)和目标节点(V,W,X,Y,Z)都没有排序.至少,排序对我来说是不可理解的.

码:

library("shiny")
library("networkD3")

ui <- fluidPage(
  column(3),
  column(6, sankeyNetworkOutput("mySankeyD")),
  column(3)
)

server <- function(input, output) {
  output$mySankeyD <- renderSankeyNetwork({
    myDf <- list(
      nodes=data.frame(name=c( "A", "B", "C", "D", "E",
                               "V", "W", "X", "Y", "Z")),
      links=data.frame(source=as.integer(c(0, 1, 2, 3, 3, 4, 4)),
                       target=as.integer(c(7, 6, 7, 8, 7, 5, 9)),
                       value =           c(1, 4, 1, 5, 1, 5, 3)
      )
    )

    sankeyNetwork(Links = myDf$links, Nodes = myDf$nodes, Source = "source",
                  Target = "target", Value = …
