Chapter 8 reveal.js Presentations

The revealjs package (El Hattab and Allaire 2017) provides an output format revealjs::revealjs_presentation that can be used to create yet another style of HTML5 slides based on the JavaScript library reveal.js. You may install the R package from CRAN:

install.packages("revealjs")

To create a reveal.js presentation from R Markdown, you specify the revealjs_presentation output format in the YAML metadata of your document. You can create a slide show broken up into sections by using the # and ## heading tags; you can also create a new slide without a header using a horizontal rule (---). For example, here is a simple slide show:

---
title: "Habits"
author: John Doe
date: March 22, 2005
output: revealjs::revealjs_presentation
---

# In the morning

## Getting up

- Turn off alarm
- Get out of bed

## Breakfast

- Eat eggs
- Drink coffee

# In the evening

## Dinner

- Eat spaghetti
- Drink wine

## Going to sleep

- Get in bed
- Count sheep

See Figure 8.1 for two sample slides.
