rray_all_equal: Strictly compare arrays

Description

Unlike rray_equal() and rray_not_equal(), these functions perform a strict comparison of two arrays, and return a single logical value. Specifically:

• Broadcasting is not performed here, as the shape is part of the comparison.

• The underlying type of the values matter, and 1 is treated as different from 1L.

• Otherwise, attributes are not compared, so dimension names are ignored.

Usage

rray_all_equal(x, y)
rray_any_not_equal(x, y)

Arguments

x, y

Vectors, matrices, arrays, or rrays.

Examples

# NOT RUN {
# This is definitely true!
rray_all_equal(1, 1)

# Different types!
rray_all_equal(1, 1L)

# Different types!
rray_all_equal(rray(1), matrix(1))

# Different shapes!
rray_all_equal(matrix(1), matrix(1, nrow = 2))

# Are any values different?
rray_any_not_equal(c(1, 1), c(1, 2))

# Is the shape different?
rray_any_not_equal(1, c(1, 2))

# Dimension names don't matter
x <- matrix(1, dimnames = list("foo", "bar"))
rray_all_equal(x, matrix(1))

# }
