Nearly everything in this course is in some way influenced by the R Community. The welcoming, public, and open culture is data science's greatest asset and I am grateful for it. This course is the intersection of many topics including programming, data wrangling, statistics, and causal inference. A thanks to the numerous individuals that have these complex topics approachable and intuitive (in particular Hadley Wickham and Josh Angrist). I am also indebted to my previous (and future) students for helping me curate and improve the material in this course. Finally, thanks to my teaching assistants Trent Young and Sarah Margaret Corley for assistance in building and maintaining this website.
