Select from a Set of Strings
A backend for the selecting functions of the 'tidyverse'.
It makes it easy to implement select-like functions in your own
packages in a way that is consistent with other 'tidyverse'
interfaces for selection.
Readme
tidyselect
Overview
The tidyselect package is the backend of functions like dplyr::select()
or dplyr::pull() as well as several tidyr verbs. It allows you to
create selecting verbs that are consistent with other tidyverse packages.
To learn about the selection syntax as a user of dplyr or tidyr, read the user-friendly Selection language reference.
To learn how to implement tidyselect in your own functions, read the Get started vignette.
To learn exactly how the tidyselect syntax is interpreted, read the Technical descrition vignette.
Installation
tidyselect is on CRAN. You can also install the development version from github with:
