To participate in both in-class exercises and homework, you will need access to a computer with the current versions of the following installed:
- the R software itself, and
 - RStudio Desktop.
 
You also need to download some files to follow this lesson:
- Make a new folder in your Desktop called 
MCB585. - Download MCB585-sample-data.zip and move the file to this folder.
 - If it’s not unzipped yet, double-click on it to unzip it. You should end up
with a new folder called 
data. - You can access this folder through your systems file explorer, or by using command-prompt navigation with:
 
Unix shell:
$ ls
$ cd Desktop/MCB585/data
Windows Command Prompt:
> dir
> cd C:\Users\<user>\OneDrive\Desktop\MCB585\data
MacOS
$ cd /Users/<username>/Desktop
