In this tutorial, I'm going to give an explanation of what pipes are and when they can be used, and then I'm going to demonstrate how useful they can be for writing neat and clear R code.
In this tutorial, I discuss how to use a handy function called group_by() for organizing and preparing your data for analysis and visualization.
