We will go through an example of a self-made function in R, and show how to document it with Roxygen2 ("roxy-gen") tags! Then, we'll go through how to test the function using the testthat package.
I also recently learned that I've been pronouncing this wrong for years LOL. Apologies for saying R-Oxygen2 multiple times!
