R: Value matching

%nin% {sjmisc} | R Documentation

## Value matching

### Description

%nin% is the complement to %in%. It looks which values in `x` do not match (hence, are not in) values in `y`.

### Usage

    x %nin% y

### Arguments

`x` | Vector with values to be matched.
`y` | Vector with values to be matched against.

### Details

See 'Details' in `match`.

### Value

A logical vector, indicating if a match was not located for each element of `x`, thus the values are `TRUE` or `FALSE` and never `NA`.

### Examples

    c("a", "B", "c") %in% letters
    c("a", "B", "c") %nin% letters

    c(1, 2, 3, 4) %in% c(3, 4, 5, 6)
    c(1, 2, 3, 4) %nin% c(3, 4, 5, 6)
