@eneqna |

Element by element inequality comparison of two data objects with NA handling.

Syntax: @eneqna(m1, m2)

m1: numeric or alphanumeric object

m2: numeric or alphanumeric object

Return: vector or matrix object

Returns the element by element test of inequality between two data objects. NAs and empty strings are treated as ordinary values for purposes of comparison.

Each element of the returned matrix is equal to 1 or 0 depending on whether the corresponding element in m1 is not equal to the corresponding element in m2.

Note m1 and m2 must be of identical dimensions.

Examples

Let X and Y be matrices. Then

= @eneqna(X, Y)

returns an binary matrix that indicates where X and Y do not match (on 0, 1, or NA).
