Numeric comparison difficulty in R

by

I’ve never been a fan of all.equal for such things. It seems to me the tolerance works in mysterious ways sometimes. Why not just check for something greater than a tolerance less than 0.05

tol = 1e-5

(a-b) >= (0.05-tol)

In general, without rounding and with just conventional logic I find straight logic better than all.equal

If x == y then x-y == 0. Perhaps x-y is not exactly 0 so for such cases I use

abs(x-y) <= tol

You have to set tolerance anyway for all.equal and this is more compact and straightforward than all.equal.
