In dplyr: A Grammar of Data Manipulation

Tidyverse selections implement a dialect of R where operators make it easy to select variables:

: for selecting a range of consecutive variables.
! for taking the complement of a set of variables.
& and | for selecting the intersection or the union of two sets of variables.
c() for combining selections.

In addition, you can use selection helpers. Some helpers select specific columns:

[everything()][tidyselect::everything]: Matches all variables.
[last_col()][tidyselect::last_col]: Select last variable, possibly with an offset.
[group_cols()]: Select all grouping columns.

Other helpers select variables by matching patterns in their names:

[starts_with()][tidyselect::starts_with]: Starts with a prefix.
[ends_with()][tidyselect::ends_with()]: Ends with a suffix.
[contains()][tidyselect::contains()]: Contains a literal string.
[matches()][tidyselect::matches()]: Matches a regular expression.
[num_range()][tidyselect::num_range()]: Matches a numerical range like x01, x02, x03.

Or from variables stored in a character vector:

[all_of()][tidyselect::all_of()]: Matches variable names in a character vector. All names must be present, otherwise an out-of-bounds error is thrown.
[any_of()][tidyselect::any_of()]: Same as all_of(), except that no error is thrown for names that don't exist.

Or using a predicate function:
