Shining a Light on learnr (Barret Schloerke Part 3)

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. Plus we get a preview of the great features coming up in the next release, and advice for Shiny developers looking to bring their skills to the next level.
