Tidy evaluation
Notice
This guide is now superseded by more recent efforts at documenting tidy evaluation in a user-friendly way. We now recommend reading:
The new Programming with dplyr vignette.
The Using ggplot2 in packages vignette.
We are keeping this bookdown guide online for posterity, but please know that it is missing a lot of advances that make tidy eval more palatable, such as the embracing operator {{ arg }}
and glue support for custom names.
