How to display HTML from RMarkdown without javascript in output

Even the simplest rmarkdown document on rendering seems to create an html document that includes javascript. I am looking to create html that can be an email body. Is there any way to render markdowns without javascript in the resulting html?

There is nothing special about the following: this is just a general example:

--- 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.

The resulting html source begins as follows:

 <!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.....

Obviously, I cut off the rest of the html, but hopefully this explains the problem.

javascript in html output format by default comes from the theme, syntax highlighting and math for equations. You can disable these three things in the header like this:

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