visNetwork在下面的 ioslides 演示文稿中，该图对我来说是空白的，但它使用 Slidy 和reveal.js 渲染得很好。我已经尝试过最新的 CRAN 和开发版本htmlwidgets和rmarkdown.
---
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)))
```
我宁愿在我当前的演示文稿中坚持使用 ioslides，因为我需要一些不坚持显示.js 的自定义 CSS。

@Esteban Moro，widgetframe绝对有帮助。不过，至少在我这边，还有工作要做。下面，我展示iotest.Rmd了 ，它会生成一个空的iotest_files. 有任何想法吗？

我在 YAML 前面的问题上试过selfcontained: false了，但小部件仍然没有出现。的结果相同selfcontained: true。
