  • If you use more than one language, or you are on a multi-language team, you will likely find Quarto’s native support for multiple languages appealing.

Why bother with Quarto?

  • Quarto combines the functionality of R Markdown, bookdown, distill, xaringan, etc. into a single consistent system with “batteries included” that reflects everything we’ve learned from R Markdown

  • You can export Quarto documents in more than 40 different file formats including Word, OpenOffice, PowerPoint, ePub, Jira Wiki, Jupyter, Observable JS, complete websites, and ebooks. R Markdown can generate some of those, but not all.

  • Quarto was designed to be multilingual, beginning with R, Python, Javascript, and Julia, with the idea that it will work even for languages that don’t yet exist.

Getting started with Quarto

Step 1: Install Quarto

  • Because Quarto isn’t a language-specific library, you install it like any other stand-alone software.

  • You can find binary downloads for Windows, macOS, and Linux on Quarto’s “Get Started” page .

  • If you’re an R user and you have an up-to-date version of RStudio, Quarto should be included by default. You don’t need to install Quarto separately.

How to use RStudio with Quarto

  • If you know R Markdown, a Quarto document will look familiar.

  • You’ll edit code and markdown in RStudio just as you would with R Markdown, and preview the rendered document in the Viewer tab as you work.

One of the biggest differences between R Markdown and Quarto is how you set up options for code chunks.

R Markdown

  • Chunk-specific options are typically put within curly braces

Quarto

  • Chunk options start off with #| (“hash pipe”) and go below the curly braces for R, Python, or Julia.
