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 NAif either x or y is NA.

S3 dispatch

vec_compare() is not generic for performance; instead it uses vec_proxy_compare() to create a proxy that is used in the comparison.

Examples

vec_compare(c(TRUE, FALSE, NA), FALSE)
#> [1]  1  0 NA
vec_compare(c(TRUE, FALSE, NA), FALSE, na_equal = TRUE)
#> [1]  1  0 -1

vec_compare(1:10, 5)
#>  [1] -1 -1 -1 -1  0  1  1  1  1  1
vec_compare(runif(10), 0.5)
#>  [1] -1  1  1  1  1  1 -1 -1  1  1
vec_compare(letters[1:10], "d")
#>  [1] -1 -1 -1  0  1  1  1  1  1  1

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