HTML Output Formats and Templates for rmarkdown Documents • rmdformats

CRAN Downloads

Note for quarto users: these templates are only suitable for RMarkdown documents. I published one quarto custom format called bookup which is a porting of the robobook template.

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.

Formats gallery

The package provides several HTML output formats. Click on any image to see an HTML output sample.

`downcute`

Taken from the docute project theme and its adaptation by John Coene. Responsive, with a dynamic table of contents and a dark theme switcher.

downcute chaos is a variation created by Zac Garland. It has a slightly different color theme, and defaults to dark mode. To use it, add a downcute_theme: "chaos" option in your YAML preamble.

`robobook`

Adapted from the bookdown theme, with Roboto family fonts. Fully responsive with dynamic table of contents and collapsible navigation.

`material`

Format taken from the Material design theme for Bootstrap 3. Document is split into pages at each <h1> header, and the table of contents allows an animated navigation between these pages (you can use the cards: false preamble parameter to disable the splitting and display all the cards at once).

`readthedown`

Adapted from the corresponding readtheorg theme of the org-html-themes project, fully responsive with dynamic table of contents and collapsible navigation.

`html_clean`

Simple and clean template with dynamic table of contents, very similar to the one from the great knitrBootstrap package by Jim Hester.

`html_docco`

Simple template, no table of contents. CSS heavily inspired from the default one of the docco project.

`lockdown`

lockdown is an exact copy of the default RMarkdown html_document template, with an added functionality : each time you click on a link to get out, you’ll see a friendly reminder to wash your hands and wear a mask. Yes, it is a (bad) attempt at a (bad) joke, sorry !

Helpers

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.

Installation

You can install the latest stable release from CRAN :

install.packages("rmdformats")

Or the latest development snapshot from GitHub :

install.packages(remotes)  # if necessary
remotes::install_github("juba/rmdformats")

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.

Options

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
output:
  rmdformats::downcute:
    self_contained: true
    thumbnails: true
    lightbox: true
    gallery: false
    highlight: tango
---
