Logical operations

• rray_and() tests whether both x and y are TRUE.

• rray_or() tests whether at least one of x and y is TRUE.

• rray_xor() tests whether exactly one of x and y is TRUE.

Usage

rray_and(x, y)

rray_or(x, y)

rray_xor(x, y)

Arguments

x, y

Logical arrays.

Value

A logical array with the common dimensions of x and y.

Details

The arrays are broadcast to common dimensions before the operation is applied.

Missing values are handled the same way as &, |, and xor().

Examples

x <- array(c(TRUE, FALSE, TRUE), c(3L, 1L))
y <- array(c(TRUE, FALSE), c(1L, 2L))

rray_and(x, y)
#>       [,1]  [,2]
#> [1,]  TRUE FALSE
#> [2,] FALSE FALSE
#> [3,]  TRUE FALSE
rray_or(x, y)
#>      [,1]  [,2]
#> [1,] TRUE  TRUE
#> [2,] TRUE FALSE
#> [3,] TRUE  TRUE
rray_xor(x, y)
#>       [,1]  [,2]
#> [1,] FALSE  TRUE
#> [2,]  TRUE FALSE
#> [3,] FALSE  TRUE

rray_and(NA, FALSE)
#> [1] FALSE
rray_or(NA, TRUE)
#> [1] TRUE
rray_xor(NA, TRUE)
#> [1] NA
