2020-03-24: Refactoring: Prepare for dplyr 1.0.0

This meetup is for you if you use dplyr or want an overview of refactoring.

dplyr 1.0.0 is comming soon. I includes great new features but also many changes that can break your code. You will likely need to change your code, and you can save time and pain of you know about Refactoring.

Content
