| equivalent {tractor.base} | R Documentation |
This function is a wrapper for isTRUE(all.equal(x,y,...{})), but
with the additional capability of doing sign-insensitive comparison.
equivalent(x, y, signMatters = TRUE, ...)
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 |
TRUE if all elements of x match all elements of
y to within tolerance, ignoring signs if required. FALSE
otherwise.
