Keeping R code DRY with functions: Don't repeat yourself! (CC096)

Don't repeat yourself or the DRY principle is one of the best practices to writing good R. When you repeat the same block of code you risk introducing errors. The solution is to write functions in R. Functions allow you to avoid repeating yourself and then you can call the function whenever you want to use that chunk of code. Pat demonstrates this by generating receiver operator characteristic (ROC) curves for data from a paper his lab published a few years ago. Pat will use RStudio and functions from the #ggplot2 package and other packages from #R and the tidyverse including #glue, #function, and more.
