Importing data into R and Intermediate Plotting

Interesting data doesn’t live inside R. Lets get data from an external file into R, and learn how to make more complex plots.

📝 Prepare:

Install the following packages: gridExtra, RColorBrewer and sjPlot.
Download the notes files for the two lessons into your Math130/notes folder.
Right click each link and save the following data sets into your Math130/data folder.

🛑 DO NOT RENAME ANYTHING If you download multiple copies of the data, do not keep the versions that have a (1) or some number in the name. Do not leave these files in your downloads folder.
