Identify Even or Odd Numbers

Description

Simple functions to test for or return the even or odd numbers.

Usage

is.even(x)
is.odd(x)
even(x)
odd(x)

Arguments

x

any numeric, but maybe makes the most sense with integers.

Details

Return a logical vector/matrix of the same dimension as the argument x telling whether each component is odd (is.odd) or even (is.even), or return just the even (even) or odd (odd) numbers from the vector/matrix. Uses %%.

Value

Returns a logical vector/matrix/array of the same dimension as x in the case of is.even and is.odd, and returns a vector of length less than or equal to x in the case of even and odd; or if no even/odd values, returns integer(0).
