 ### The Code
 
 The gray area below is a code chunk that will set up our packages and data. You can also run the code within the editor area by pressing the green play button. Don't worry right now about what the code is doing, we will cover this later. We just want you to get used to RStudio and RMarkdowns. This dataset is one we'll be working with quite a lot in the lectures. It contains county-level data about ER visits for heat-related illnesses in Colorado for the years 2011-2022.
