我正在尝试创建一个闪亮的仪表板（R 3.1.0 / shiny 0.12.0 / shinydashboard 0.5.0）。我已成功创建布局，并决定在仪表板侧边栏中使用多个选项卡。

侧边栏由多个选项卡组成，每个选项卡显示一组特定的图到目前为止我所做的简单屏幕截图

我正在尝试为这些图添加一个下载按钮，但我必须将它添加到标题中（以便所有选项卡都可以使用它）。我知道“messageItem”选项，但无法使用它。

有人可以帮忙吗。任何您认为可以的替代方法都是最受欢迎的。

提前致谢

这是同时下载所有绘图的另一种方法。您可以创建一个下载处理程序按钮，该按钮将同时以 pdf/ppt 格式下载所有图。示例代码如下：

output$downloadReport <- downloadHandler(

    filename = "You report.pdf",
    content = function(file) {
      pdf(file)

      ## If you have displayed some Datatables in any of your tabs
      pushViewport(viewport(layout = grid.layout(3, 2, heights = unit(c(0.5, 5, 5), "null")))) 
      sample<- sampledatatable() ## Function which you have made in server.R
      sample<- grid.table(sample)
      vp = viewport(layout.pos.row = 2, layout.pos.col = 1:2)
      grid.text("Your Datatable", vp = viewport(layout.pos.row = 1, layout.pos.col = 1:2))
      grid.newpage()

      print(plot1()) # Function for the plot you made it in Server.R
      print(plot2())

      dev.off()
    }
  )
