The Opposite of %in%

Description

Duh.

Usage

1
x %out% y

Arguments

x

vector or NULL: the values to be matched.

y

vector or NULL: the values to be matched.

Details

That %out% never returns NA makes it particularly useful in if conditions.

Value

A logical vector of the same length as x, indicating if a match was located for each element of x: thus the values are TRUE or FALSE and never NA.
