    • Alternatively (and preferably now), if you’re using R on your own computer, download this file, unzip it, and double click on the file named problem-set-5.Rproj: You’ll need to make sure you have these packages installed on your computer: tidyverse, ggdag. If you try to load one of those packages with library(tidyverse) or library(ggdag), etc., and R gives an error that the package is missing, use the “Packages” panel in RStudio to install it.

  3. Complete the tasks given in the R Markdown file.

  4. When you’re all done, click on the “Knit” button at the top of the editing window and create a PDF or Word document of your problem set. Upload that file to iCollege.
