## Usual Practice
1. If you are asked to install any packages install them by clicking the "Install" button in the yellow banner.
2. Always start by knitting any `.Rmd` file to make sure everything looks good. 
3. Always run R chunks provided to you before moving onto the rest of the document.
4. Write the [YAML part of](https://cosmos-uci-dshs.github.io/dshs-slides/week01/01b-intro-r.html#26) this document.
