Consider the R following code:
x = seq(0,.6,by=0.2)
stopifnot( x == c(0, 0.2, 0.4, 0.6)) # does not stop
x = seq(0,.8,by=0.2)
stopifnot( x == c(0, 0.2, 0.4, 0.6, 0.8)) # stops
Why aren't x and c(...) equivalent in the second case?

4The fifth element is (spoiler) actually a woman. – Richie Cotton Aug 30 '16 at 11:27

@RichieCotton: Would it be correct to use `all.equal`instead of `==`? – Jim G. Aug 30 '16 at 11:52

1Yes. Or possibly `isTRUE(all.equal(x, y))`, depending upon what you are doing. – Richie Cotton Aug 30 '16 at 12:07
