带有 TableTools 和其他扩展的 R 闪亮数据表

Question

我正在尝试让 dataTables TableTools 和其他扩展与 Shiny 一起使用。我找到了一个解释如何做的网站：

https://gist.github.com/bearloga/8327428

但我无法让它工作。 addResourcePath 在我的脚本中不起作用，所以我从完整路径中获取。即使这样，似乎采购 DataTables 和扩展也没有效果，而且我只得到一个基本表，而没有 TableTools 或任何其他扩展工作。我知道 tags$script 条目正在工作，因为如果我将窗口设置得足够小，我会从下面的 HTML 中收到 Screen too small 警告。

有什么想法吗？

#### ui.R
suppressWarnings(suppressPackageStartupMessages(library("ggplot2", lib.loc="/opt/thirdparty/R/R-3.1.0/lib64/R/library")))
shinyUI = basicPage(
    h1('Diamonds DataTable with TableTools'),
    tagList(
    singleton(tags$head(tags$script(src='/opt/development/tools/webdev/shiny/datatables/DataTables-1.10.0/media/js/jquery.dataTables.js',type='text/javascript'))),
    singleton(tags$head(tags$script(src='/opt/development/tools/webdev/shiny/datatables/TableTools-2.2.1/js/dataTables.tableTools.js',type='text/javascript'))),
    singleton(tags$head(tags$script(src='/opt/development/tools/webdev/shiny/datatables/ColReorder-1.1.1/js/dataTables.colReorder.js',type='text/javascript'))),
    singleton(tags$head(tags$link(href='/opt/development/tools/webdev/shiny/datatables/TableTools-2.2.1/css/dataTables.tableTools.css',rel='stylesheet',type='text/css'))),
    singleton(tags$script(HTML("if (window.innerHeight < 400) alert('Screen too small');")))
    ),
    dataTableOutput("mytable")
)

您需要链接到正确的库版本。可以在 http://cdnjs.com/libraries/datatables 找到指向 data.table 1.9.4 的链接。 http://cdnjs.com/libraries/datatables-tabletools 上指向 tabletools 2.1.5 的链接

library(shiny)
library(ggplot2)
runApp(
  list(ui = basicPage(
    h1('Diamonds DataTable with TableTools'),
    tagList(
      singleton(tags$head(tags$script(src='//cdnjs.cloudflare.com/ajax/libs/datatables/1.9.4/jquery.dataTables.min.js',type='text/javascript'))),
      singleton(tags$head(tags$script(src='//cdnjs.cloudflare.com/ajax/libs/datatables-tabletools/2.1.5/js/TableTools.min.js',type='text/javascript'))),
      singleton(tags$head(tags$script(src='//cdnjs.cloudflare.com/ajax/libs/datatables-tabletools/2.1.5/js/ZeroClipboard.min.js',type='text/javascript'))),
      singleton(tags$head(tags$link(href='//cdnjs.cloudflare.com/ajax/libs/datatables-tabletools/2.1.5/css/TableTools.min.css',rel='stylesheet',type='text/css'))),
      singleton(tags$script(HTML("if (window.innerHeight < 400) alert('Screen too small');")))
    ),
    dataTableOutput("mytable")
  )
  ,server = function(input, output) {
    output$mytable = renderDataTable({
      diamonds[,1:6]
    }, options = list(
      "sDom" = 'T<"clear">lfrtip',
      "oTableTools" = list(
        "sSwfPath" = "//cdnjs.cloudflare.com/ajax/libs/datatables-tabletools/2.1.5/swf/copy_csv_xls.swf",
        "aButtons" = list(
          "copy",
          "print",
          list("sExtends" = "collection",
               "sButtonText" = "Save",
               "aButtons" = c("csv","xls")
          )
        )
      )
    )
    )
  })
