我如何通过运行多个图表来覆盖输出显示选项,以使输出结果为2x2矩阵型网格布局。

require(rCharts)
require(shiny)
require(data.table)
runApp(list(
  ui = mainPanel( span="span6", 
    showOutput("chart2", "Highcharts"),
    showOutput("chart3", "Highcharts"),
    showOutput("chart4", "Highcharts")
    ),
  server = function(input, output){
      output$chart3 <- renderChart({
      a <- hPlot(Pulse ~ Height, data = MASS::survey, type = "bubble", title = "Zoom demo", subtitle = "bubble chart", size = "Age", group = "Exer")
      a$chart(zoomType = "xy")
      a$chart(backgroundColor = NULL)
      a$set(dom = 'chart3')
      return(a)
    })
    output$chart2 <- renderChart({
      survey <- as.data.table(MASS::survey)
      freq <- survey[ , .N, by = c('Sex', 'Smoke')]
      a <- hPlot(x = 'Smoke', y = 'N', data = freq, type = 'column', group = 'Sex')
      a$chart(backgroundColor = NULL)
      a$set(dom = 'chart2')
      return(a)
    })
    output$chart4 <- renderChart({
      survey <- as.data.table(MASS::survey)
      freq <- survey[ , .N, by = c('Smoke')]
      a <- hPlot(x = "Smoke", y = "N", data = freq, type = "pie")
      a$plotOptions(pie = list(size = 150))
      a$chart(backgroundColor = NULL)
      a$set(dom = 'chart4')
      return(a)
    })
  }
))

将ui更改为:

ui = bootstrapPage(mainPanel( 
      div(class = "row",
        div(showOutput("chart2", "Highcharts"), class = "span4"),
        div(showOutput("chart3", "Highcharts"), class = "span4")
      ),
      div(class = "row",
        div(showOutput("chart4", "Highcharts"), class = "span4")
      )
    ))

添加 bootstrapPage 告诉shing使用引导库。看看 http://getbootstrap.com/2.3.2/scaffolding.html 了解“脚手架”的概念。 mainPanel 具有默认为8的宽度选项。这是引导中的span8。上面的代码并不理想,但希望它是一个开始。

编辑:用于全屏

ui = bootstrapPage(mainPanel(width = 12,  
      div(class = "row",
        div(showOutput("chart2", "Highcharts"), class = "span6"),
        div(showOutput("chart3", "Highcharts"), class = "span6")
      ),
      div(class = "row",
        div(showOutput("chart4", "Highcharts"), class = "span6")
      )
    ))

注意,mainPanel(…,width=width)只是宽度跨度为的div的一个方便函数。

R Shiny的另一个解决方案(没有HTML的外部知识)是使用列的思想。

ui = mainPanel(fluidPage(
    fluidRow(
      column(width=6, 
             showOutput("chart2", "Highcharts"),
             showOutput("chart3", "Highcharts")
    ),
    fluidRow(
      column(width=6, 
             showOutput("chart4", "Highcharts") 
        )
      )
    )
  )),
