RStudio v2022.07 and later includes support for editing and preview of Quarto documents (the documentation below assumes you are using this build or a later version). You can override the version of R used by Quarto by setting the QUARTO_R environment variable. In addition, on Windows when R is not found on the PATH, the registry will be scanned for the current R version. Quarto will select a version of R by looking on the system PATH. Installation of the rmarkdown package will also install the knitr package so you will have everything required to render documents containing R code. You can render Quarto documents in a variety of ways:įrom the system shell using the quarto render command: When a Quarto document is rendered, R code blocks are automatically executed. There are many options which control the behavior of code execution and output, you can read more about them in the article on Execution Options.

This document results in the following rendered output: These are cell level options that make the figure cross-referenceable. You’ll note that there are some special comments at the top of the code block.
