Question

我发现了这个 - http://shiny.rstudio.com/gallery/download-knitr-reports.html - 一个很棒的例子，可以创建静态PDF，HTML和Word文档。

我希望能够做的是上传一个数据集，然后生成一个模板化的闪亮演示文稿。我尝试了多条路线但收效甚微。我得到的最远的是将此代码包含在我的降价文件中：

date: "Wednesday, September 03, 2014"
output:
  ioslides_presentation:
    self_contained: false
    lib_dir: libs
runtime: shiny

尝试下载示例.HTML文件时，出现此错误path for html_dependency not provided。我在追逐目前不存在的功能吗？如果没有，有没有人有一些建议？

提前致谢！

## Shiny Presentation

This R Markdown presentation is made interactive using Shiny. The viewers of the presentation can change the assumptions underlying what's presented and see the results immediately. 

To learn more, see [Interative Documents](http://rmarkdown.rstudio.com/authoring_shiny.html).

## Slide with Interactive Plot

```{r, echo=FALSE}
inputPanel(
  selectInput("n_breaks", label = "Number of bins:",
              choices = c(10, 20, 35, 50), selected = 20),

  sliderInput("bw_adjust", label = "Bandwidth adjustment:",
              min = 0.2, max = 2, value = 1, step = 0.2)
)

renderPlot({
  hist(faithful$eruptions, probability = TRUE, breaks = as.numeric(input$n_breaks),
       xlab = "Duration (minutes)", main = "Geyser eruption duration")

  dens <- density(faithful$eruptions, adjust = input$bw_adjust)
  lines(dens, col = "blue")
})
```

我是否在追逐目前尚不存在的功能？

一点点。： - ）

交互式闪亮演示文稿（和文档）无法保存为HTML。他们需要一台服务器来运行它们包含的R代码。发生的事情是您的应用程序正在尝试将交互式演示文稿呈现为静态HTML文件，这是不受支持的。

简短的回答是，您需要一个“运行”代替“下载”，它会调用rmarkdown::run而不是rmarkdown::render。

如果您正在寻找可下载的资产，那么您可以做的最好的事情就是下载.Rmd本身，并为当前的UI状态添加适当的字符串替换;然后可以随时使用rmarkdown::run运行.Rmd。

从闪亮的应用程序创建闪亮的演示文稿？
