R: Compare two vectors

vec_compare {vctrs} | R Documentation

## Compare two vectors

### Description

Compare two vectors

### Usage

    vec_compare(x, y, na_equal = FALSE, .ptype = NULL)

### Arguments

`x, y` | Vectors with compatible types and lengths.
`na_equal` | Should `NA` values be considered equal?
`.ptype` | Override to optionally specify common type

### Value

An integer vector with values -1 for `x < y`, 0 if `x == y`, and 1 if `x > y`. If `na_equal` is `FALSE`, the result will be `NA` if either `x` or `y` is `NA`.

### S3 dispatch

`vec_compare()` is not generic for performance; instead it uses `vec_proxy_compare()` to

### Examples

    vec_compare(c(TRUE, FALSE, NA), FALSE)
    vec_compare(c(TRUE, FALSE, NA), FALSE, na_equal = TRUE)

    vec_compare(1:10, 5)
    vec_compare(runif(10), 0.5)
    vec_compare(letters[1:10], "d")

    df <- data.frame(x = c(1, 1, 1, 2), y = c(0, 1, 2, 1))
    vec_compare(df, data.frame(x = 1, y = 1))
