bc.rel

Broadcasted General Relational Operators

Description

The bc.rel() function performs broadcasted general relational operations on 2 arrays.

Usage

bc.rel(x, y, op, ...)

## S4 method for signature 'ANY'
bc.rel(x, y, op)

Arguments

x, y conformable vectors/arrays of any atomic type.

op a single string, giving the relational operator.
Supported relational operators: ==, !=, <, >, <=, >=.

… further arguments passed to or from methods.

Value

A logical array as a result of the broadcasted general relational operation.

Examples

library("broadcast")


x.dim <- c(4:2)
x.len <- prod(x.dim)
x.data <- sample(c(NA, 1.1:1000.1), x.len, TRUE)
x <- array(x.data, x.dim)
y <- array(1:50, c(4,1,1))
