This R package provides ready-to-use HTML output formats and templates for RMarkdown documents. The goal is to produce clean documents “out of the box”, with or without the RStudio IDE.

The package also provides RStudio document templates to easily generate an empty and ready to use rmarkdown file with several configuration directives.

It also provides the pilltabs() helper function, which allows to display a crosstab dynamically. See one of the output samples for a live example.


You can install the latest stable release from CRAN :


Or the latest development snapshot from GitHub :

install.packages(remotes)  # if necessary

Creating a new document

Just create a new Rmd file and add the following in your YAML preamble :

output: rmdformats::<template name>

Within RStudio , you can also choose File > New File... > R Markdown..., then select From Template. You should then be able to create a new document from one of the package templates.


Depending on the features provided by the template, you can add the following options to your YAML preamble. Look at the template function help page for a valid list :

  • fig_width : figures width, in inches
  • fig_height : figures height, in inches
  • fig_caption : toggle figure caption rendering
  • highlight : syntax highlighting
  • thumbnails : if TRUE, display content images as thumbnails
  • lightbox : if TRUE, add lightbox effect to content images
  • gallery : if TRUE, add navigation between images when displayed in lightbox
  • use_bookdown : if TRUE, will use bookdown instead of rmarkdown for HTML rendering, thus providing section numbering and cross references.
  • embed_fonts : if TRUE (default), use local files for fonts used in the template instead of links to Google Web fonts. This leads to bigger files but ensures that the fonts are available
  • additional aguments are passed to the base html_document RMarkdown template

Example preamble :

title: "My document"
date: "`r Sys.Date()`"
author: John Doe
    self_contained: true
    thumbnails: true
    lightbox: true
    gallery: false
    highlight: tango


  • Magnific popup lightbox plugin
  • The CSS for the html_docco format is heavily inspired from the default one of the docco project.
  • The CSS and JavaScript for readthedown is adapted from the corresponding readtheorg theme of the org-html-themes project, which is itself inspired by the Read the docs Sphinx theme.
  • The CSS and JavaScript for material has been taken from the Material design theme for Bootstrap 3 project and its presentation page.
  • The CSS for robobook is directly derived from the bookdown project template.
  • The CSS for downcute is directly derived from the default theme of the docute project and its adaptation by John Coene for some of its projects documentation.
  • The downcute chaos theme has been created by Zac Garland.
  • JavaScript and HTML code for code folding and tabbed sections are taken from the RStudio’s default rmarkdown HTML template.
  • The html_clean styling and features are very similar to the ones from the knitrBootstrap package by Jim Hester.
