These quoting functions signal to scoped filtering verbs (e.g. filter_if() or filter_all()) that a predicate expression should be applied to all relevant variables. The all_vars() variant takes the intersection of the predicate expressions with & while the any_vars() variant takes the union with |.

all_vars(expr)

any_vars(expr)

## Arguments

expr A predicate expression. This variable supports unquoting and will be evaluated in the context of the data frame. It should return a logical vector. This argument is automatically quoted and later evaluated in the context of the data frame. It supports unquoting. See vignette("programming") for an introduction to these concepts.

vars() for other quoting functions that you can use with scoped verbs.
