equivalent: Test two numeric vectors for equivalence

Description

Test two numeric vectors for equivalence.

Usage

equivalent(x, y, signMatters = TRUE, ...)

Arguments

x

The first numeric vector.

y

The second numeric vector.

signMatters

Logical value: if FALSE then equivalence in absolute value is sufficient.

...

Additional arguments to all.equal, notably tolerance.

Value

• TRUE if all elements of x match all elements of y to within tolerance, ignoring signs if required. FALSE otherwise.

Details

This function is a wrapper for isTRUE(all.equal(x,y,...)), but with the additional capability of doing sign-insensitive comparison.

Examples

equivalent(c(-1,1), c(1,1))  # FALSE
equivalent(c(-1,1), c(1,1), signMatters=FALSE)  # TRUE
equivalent(1:2, 2:3, tolerance=2)  # TRUE
