如何在输出中没有 javascript 的情况下从 RMarkdown 渲染 HTML

Question

即使是最简单的 rmarkdown 文档在呈现时似乎也会创建一个包含 javascript 的 html 文档。我希望创建可以作为电子邮件正文的 html。有没有办法在结果 html 中呈现没有 javascript 的降价？

以下没有什么特别之处，只是一个通用的例子：

---
title: "Sample"
author: "JKGrain"
date: "March 31, 2015"
output: html_document
---

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>.

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}
summary(cars)
```

You can also embed plots, for example:

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

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

生成的 html 来源是这样开始的：

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

<meta charset="utf-8">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta name="generator" content="pandoc" />

<meta name="author" content="JKGrain" />

<meta name="date" content="2015-03-31" />

<title>Sample</title>

<script src="data:application/x-javascript,%2F%2A%21%20jQuery%20v1%2E11.....

显然，我已经剪掉了 html 的其余部分，但希望这能解释问题。

默认 html 输出格式中的 javascript 来自主题、语法突出显示和方程式的 mathjax。您可以像这样在 header 中禁用这三件事：

---
output: 
    html_document:
        theme: null
        highlight: null
        mathjax: null
