Question

我正在尝试使用networkD3和闪亮来可视化一些数据。我希望在单击图表中的节点时执行操作。我正在使用diagonalNetwork函数，如下面的代码所示。

forceNetwork函数可以选择在单击节点时使clickaction响应。但是，我找不到diagonalNetwork函数的类似选项。还有其他方法可以实现吗？

#### Load necessary packages and data ####
library(shiny)
library(networkD3)

data(MisLinks)
data(MisNodes)

hc <- hclust(dist(USArrests), "ave")
URL <- paste0(
  "https://cdn.rawgit.com/christophergandrud/networkD3/",
  "master/JSONdata//flare.json")



## Convert to list format
Flare <- jsonlite::fromJSON(URL, simplifyDataFrame = FALSE)


#### Server ####
server <- function(input, output) {

  output$simple <- renderDiagonalNetwork({
    diagonalNetwork(List = Flare, fontSize = 10, opacity = 0.9)
  })  


  output$force <- renderForceNetwork({
    forceNetwork(Links = MisLinks, Nodes = MisNodes, Source = "source",
                 Target = "target", Value = "value", NodeID = "name",
                 Group = "group", opacity = input$opacity)


  })

  ## 
  #dendroNetwork(hc, height = 600)
 # 
#  dendroNetwork(hc, height = 500, width = 800, fontSize = 10,
#                linkColour = "#ccc", nodeColour = "#fff", nodeStroke = "steelblue",
#                textColour = "#111", textOpacity = 0.9, textRotate = NULL,
#                opacity = 0.9, margins = NULL, linkType = c("elbow", "diagonal"),
#                treeOrientation = c("horizontal", "vertical"), zoom = FALSE)



}

#### UI ####

ui <- shinyUI(fluidPage(

  titlePanel("Shiny networkD3 "),

  sidebarLayout(
    sidebarPanel(
      sliderInput("opacity", "Opacity (not for Sankey)", 0.6, min = 0.1,
                    max = 1, step = .1)
    ),
    mainPanel(
      tabsetPanel(
        tabPanel("Simple Network", diagonalNetworkOutput("simple")),
        tabPanel("Force Network", forceNetworkOutput("force"))
      )
    )
  )
))

#### Run ####
shinyApp(ui = ui, server = server)

您可以使用<card ng-repeat="person in vm.persons | unique: 'PTSNumber'" name="{{person.Firstname}} {{person.Surname}}" theme="user" ptsnumber="{{ person.PTSNumber }}" isUser="{{ true }}" ng-click="vm.setUser(person.PTSNumber, person.Firstname, person.Surname, $event)"></card>的{{1}}函数将htmlwidgets事件附加到此类节点...

onRender

闪亮＆amp; networkD3响应节点点击
