Question

我正试图在其中一个标签中为散点图创建一个闪亮的rChart ..以下是ui.R中的代码片段

  mainPanel( 
    tabsetPanel(
      tabPanel("Tab 1","Type of chart",textOutput("caption"),"Chart", plotOutput("mpgPlot")),
      tabPanel("Tab 2","Type of chart",showOutput("RPlot", "Highcharts"))
    )
  )

以下是server.R代码

  output$RPlot <- renderChart({
    p <- nPlot(mpg ~ wt, group = 'cyl', data = mtcars, type = 'scatterChart')
    return(p)
  })

代码没有给出错误但没有显示rChart ..
