From purrr v0.2.2.2
by Lionel Henry

##### Negate a predicate function.

Negate a predicate function.

##### Usage

`negate(.p)`

##### Arguments

- .p
A single predicate function, a formula describing such a predicate function, or a logical vector of the same length as

`.x`

. Alternatively, if the elements of`.x`

are themselves lists of objects, a string indicating the name of a logical element in the inner lists. Only those elements where`.p`

evaluates to`TRUE`

will be modified.

##### Value

A new predicate function.

##### Examples

```
# NOT RUN {
x <- transpose(list(x = 1:10, y = rbernoulli(10)))
x %>% keep("y") %>% length()
x %>% keep(negate("y")) %>% length()
# Same as
x %>% discard("y") %>% length()
# }
```
