在下面的 ioslides 演示中，visNetwork 图表对我来说是空白的，但它在 Slidy 和 Reveal.js 中渲染得很好。我已经尝试了 htmlwidgets 和 rmarkdown 的最新 CRAN 和开发版本。
---
title: "slides"
output: ioslides_presentation
---
## The HTML widget should render.
```{r}
library(visNetwork, quietly = TRUE)
visNetwork(data.frame(id = 1:3), data.frame(from = c(1,2), to = c(1,3)))
```
我宁愿在当前演示文稿中坚持使用 ioslides，因为我需要一些不坚持 Reveal.js 的自定义 CSS。

@Esteban Moro，widgetframe 绝对有帮助。但仍有工作要做，至少对我来说是这样。下面，我展示了 iotest.Rmd，它生成一个空的 iotest_files。有什么想法吗？

我在 YAML Front Matter 中尝试了 selfcontained: false，但小部件仍然没有出现。 selfcontained: true 的结果相同。
---
title: "slides"
output:
ioslides_presentation:
selfcontained: false

## The HTML widget should render.
```{r}
library(visNetwork, quietly = TRUE)
library(widgetframe)
frameWidget(visNetwork(data.frame(id = 1:3), data.frame(from = c(1,2), to = c(1,3))))
```
最佳答案
对于ioslides，我使用R中的widgetframe库解决了它
library(visNetwork, quietly = TRUE)
library(widgetframe)
frameWidget(visNetwork(data.frame(id = 1:3), data.frame(from = c(1,2), to = c(1,3))))

这是一个适合我的最小示例:
---
title: "slides"
output:
ioslides_presentation:
self_contained: FALSE
---
```{r setup, include=F}
knitr::opts_chunk$set(widgetframe_widgetsdir = 'widgets')
library(visNetwork, quietly = TRUE)
library(widgetframe)
```
## The HTML widget should render.
```{r}
frameWidget(visNetwork(data.frame(id = 1:3),
data.frame(from = c(1,2), to = c(1,3))))
```
关于r - HTML 小部件不会在 ioslides 演示文稿中呈现，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45103219/
