DataCamp is a web-based interactive R learning platform that offers free R tutorials through learning-by-doing. It breaks the different programming assignments down into many short exercises, and provides you with hints and instant feedback on how to perform even better. It's a great initiative to help you understand the underlying logic of the R code explained in the lectures. If you have any questions or feedback on the platform itself, you can always send them a message via Facebook or Twitter!
