Primitive All Reduction

Source: R/primitives.R
prim_reduce_all.Rd

Performs logical AND along the specified dimensions.

Usage

prim_reduce_all(operand, dims, drop = TRUE)

Arguments

operand

(arrayish)
Arrayish value of boolean data type.

dims

(integer())
Dimensions to reduce over.

drop

(logical(1))
Whether to drop the reduced dimensions from the output shape. If TRUE, the reduced dimensions are removed. If FALSE, the reduced dimensions are set to 1.

Value

arrayish
Boolean array. Never ambiguous. When drop = TRUE, the shape is that of operand with dims removed. When drop = FALSE, the shape is that of operand with dims set to 1.
