Equality

vec_equal() tests if two vectors are equal.

Usage

vec_equal(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

A logical vector the same size as the common size of x and y. Will only contain NAs if na_equal is FALSE.

Dependencies

• vec_cast_common() with fallback

• vec_recycle_common()

• vec_proxy_equal()

Examples

vec_equal(c(TRUE, FALSE, NA), FALSE)
#> [1] FALSE  TRUE    NA
vec_equal(c(TRUE, FALSE, NA), FALSE, na_equal = TRUE)
#> [1] FALSE  TRUE FALSE

vec_equal(5, 1:10)
#>  [1] FALSE FALSE FALSE FALSE  TRUE FALSE FALSE FALSE FALSE FALSE
vec_equal("d", letters[1:10])
#>  [1] FALSE FALSE FALSE  TRUE FALSE FALSE FALSE FALSE FALSE FALSE

df <- data.frame(x = c(1, 1, 2, 1), y = c(1, 2, 1, NA))
vec_equal(df, data.frame(x = 1, y = 2))
#> [1] FALSE  TRUE FALSE    NA
