We conclude our multi-part series with RStudio software engineer Barret Schloerke with an in-depth look at the learnr package and how Shiny plays a huge role in powering the many features and extensibility available! Barret walks us through two showcases of learnr in action with the RStudio primer tutorials as well as the eye-catching naniar missing values tutorial by Allison Horst.
