R: Approximate Percent Equality Testing Function

omxCheckWithinPercentError {OpenMx} | R Documentation

## Approximate Percent Equality Testing Function

### Description

This function tests whether two numeric vectors or matrixes are approximately equal to one another, within a specified percentage.

### Usage

    omxCheckWithinPercentError(a, b, percent = 0.1)

### Arguments

`a` | a numeric vector or matrix.
`b` | a numeric vector or matrix.
`percent` | a non-negative percentage.

### Details

Arguments ‘a’ and ‘b’ must be of the same type, ie. they must be either vectors of equal dimension or matrices of equal dimension. The two arguments are compared element-wise for approximate equality. If the absolute value of the difference of any two values is greater than the percentage difference of ‘a’, then an error will be thrown.

    omxCheckWithinPercentError(matrix(3, 3, 3), matrix(4, 3, 3), percent = 150)

    # Throws an error
    try(omxCheckWithinPercentError(c(1, 2, 3), c(1.1, 1.9 ,3.0), percent = 0.01))
