18.3 Using a new format
New formats should be stored within a package and installed onto your local system. This allows the format to be provided to the document YAML. Assuming our example formatquarterly_report is in a package namedmypackage, we can use it as follows:
---title: "Habits"output: mypackage::quarterly_report: toc: true---This means to use thequarterly_report() function defined inmypackage as the output format, and to passtoc = TRUE as a parameter to the function.
