如何将 Leaflet (for R)-output 包含到 RMarkdown 演示文稿中？

Question

根据文档，使用 R 的“leaflet”包创建的 Leaflet 输出可以包含在 RMarkdown 中。

这在 RMarkdown 输出为 html 时有效：

---
title: "Rmarkdown HTML including Leaflet"
output: html_document
---

Show "Leaflet for R" within html: works.

```{r}
library(leaflet)
leaflet() %>%
  addTiles %>% # Add default OpenStreetMap map tiles
  setView(lng = 5.0, lat = 51.0, zoom = 6)
```

但是当 RMarkdown 输出是演示文稿时失败：

---
title: "Rmarkdown Presentation including Leaflet"
output: 
  revealjs::revealjs_presentation
---

Show "Leaflet for R" within Rmarkdown presentation: fails.

```{r}
library(leaflet)
leaflet() %>%
  addTiles %>% # Add default OpenStreetMap map tiles
  setView(lng = 5.0, lat = 51.0, zoom = 6)
```

我的目标是创建一个包含传单输出的演示文稿。如何做到这一点？

这不是一个真正的解决方案，而是一个解决方法：从 Revealjs 演示文稿类型更改为 ioslides 时，Leaflet 输出显示在演示文稿中。但布局和交互性并非完美无缺。

title: "Rmarkdown Presentation including Leaflet"

output: 
  ioslides_presentation

Show "Leaflet for R" within Rmarkdown "ioslides" presentation: works, but not flawless.

```{r echo=FALSE}
library(leaflet)
leaflet() %>%
  addTiles %>% # Add default OpenStreetMap map tiles
  setView(lng = 5.0, lat = 51.0, zoom = 6)
```

由于我更喜欢​​使用 Revealjs 而不是 ioslides，因此我希望有人能够提供一个可以与 Revealjs 配合使用的更好的解决方案。
