问题描述

是否可以在 R Markdown 中嵌入 YouTube 视频?到目前为止，我所拥有的是

Is it possible to embed a YouTube video in a R Markdown? So far what I have is

<a href="http://www.youtube.com/watch?feature=player_embedded&v=Q8rakpF7duU
" target="_blank"><img src="http://img.youtube.com/vi/Q8rakpF7duU/0.jpg" 
alt="IMAGE ALT TEXT HERE" width="240" height="180" border="10" /></a>

但它只添加了一个图像.单击此图像会将我带到开始播放视频的浏览器.有没有办法让我在 markdown 文档中播放视频?

but it only adds an image. Clicking on this image takes me to my browser where the video starts playing. Is there a way that allows me to play the video in the markdown document itself?

推荐答案

您将需要使用 iframe.例如在基本 RMD 模板中添加 Markdown 视频:

You will need to use iframe. For example adding a markdown video to the basic RMD template:

---
title: "iframe"
author: "Example"
date: "22 July 2016"
output: html_document
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

## R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see <http://rmarkdown.rstudio.com>.

<iframe width="560" height="315" src="https://www.youtube.com/embed/6A5EpqqDOdk" frameborder="0" allowfullscreen></iframe>

When you click the **Knit** button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

```{r cars}
summary(cars)
```

## Including Plots

You can also embed plots, for example:

```{r pressure, echo=FALSE}
plot(pressure)
```

Note that the `echo = FALSE` parameter was added to the code chunk to prevent printing of the R code that generated the plot.

请注意，视频不会出现在预览窗口中，但在连接到互联网的浏览器中查看时会出现.

Note that the video will not appear in the preview window but will when viewed in a browser connected to the internet.
