This is a companion discussion topic for the original entry at:

Tidy eval: Programming with dplyr, tidyr, and ggplot2


Tidy evaluation is a new framework for non-standard evaluation that will be used throughout tidyverse. In this talk, I’ll introduce you to the problem that tidy eval solves, illustrated with examples of the various approaches used in R. I’ll then explain the most important components so that you can start writing your own functions instead of copying and pasting tidyr and dplyr code. I’ll finish with a small shiny app that shows how tidy eval is a natural fit for handling user input.
