我正在使用networkD3和闪亮来可视化一些数据。我有一个diagonalNetwork由networkD3. 但是，我希望树垂直显示。networkD3似乎没有旋转对角网络的选项。

我可以旋转一个tabPanel吗shiny？

我在下面添加了代码。如果可能的话，我希望能够旋转diagonalNetwork(). 如果没有，我可以旋转整个tabPanel吗？

我注意到networkD3'sforceNetwork有一个onclick选项，是否可以以与 a 相同的方式响应节点点击diagonalNetwork？

#### 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)

将此添加到您的 server.R

注意：包含网络的 div 的 id 是simple.

  observe({
    runjs("
          var rotated = false;
          var div = document.getElementById('simple');

          deg = rotated ? 0 : 90

          div.style.webkitTransform = 'rotate('+deg+'deg)'; 
          div.style.mozTransform    = 'rotate('+deg+'deg)'; 
          div.style.msTransform     = 'rotate('+deg+'deg)'; 
          div.style.oTransform      = 'rotate('+deg+'deg)'; 
          div.style.transform       = 'rotate('+deg+'deg)';

          rotated = !rotated;
          div.style.position = 'absolute';
          div.style.width = 1200+'px';
          div.style.height = 1200+'px';
    ")
  })

在您的 ui.R 中，您必须包含useShinyjs()并且不要忘记加载包shinyjs。可以在此处找到有关在 JS 中旋转的信息：Rotate a div using javascript

在networkD3(v0.4.9000 @ 2017.08.30) 的当前开发版本中，有一个新treeNetwork()功能内置了这个功能和许多其他新功能（它们也是可折叠的）。

您可以使用...安装当前的开发版本

devtools::install_github("christophergandrud/networkD3")

并绘制一个垂直（向下扩展）对角线图...

library(networkD3)
library(jsonlite)

URL <- paste0("https://cdn.rawgit.com/christophergandrud/networkD3/",
              "master/JSONdata//flare.json")
Flare <- jsonlite::fromJSON(URL, simplifyDataFrame = FALSE)

treeNetwork(Flare, type = "tidy", direction = "down")

仍然有很多错误需要解决，例如文本标签的放置和旋转，所以我们会很感激测试、填写问题/错误报告和/或拉取请求。https://github.com/christophergandrud/networkD3
