带有reveal.js的R htmlwidgets

Question

如何在reveal.js和Rmarkdown中使用优秀的htmlwidgets(例如http://rstudio.github.io/leaflet/)？

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，您需要在标头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。
