R htmlwidgets 与reveal.js

Question

如何将出色的 htmlwidgets（例如 http://rstudio.github.io/leaflet/）与reveal.js 和 Rmarkdown 一起使用？

这个mwe（不是rev​​eal.js）有效：

---
title: "Maptest 1"
output: html_document
---

##  Map

```{r, echo=FALSE}
library(leaflet)
m <- leaflet()
m <- addTiles(m)
m <- addMarkers(m, lng=174.768, lat=-36.852, popup="The birthplace of R")
m
```

但是这个没有：

---
title: "Maptest 2"
output: revealjs::revealjs_presentation
---

##  Map

```{r, echo=FALSE}
library(leaflet)
m <- leaflet()
m <- addTiles(m)
m <- addMarkers(m, lng=174.768, lat=-36.852, popup="The birthplace of R")
m
```

我重新使用了 htmlwidgets-webpage 中的示例，reveal.js-template 来自https://github.com/jjallaire/revealjs

要使用reveal.js，您需要在标题中指定框架和扩展小部件。还要确保您拥有最新版本的 slidify 和 htmlwidgets。
