...ble ### I also tried binding the two vectors in a data.frame, with no avail. I did find a hack, creating two new vectors inside the function and creating a fresh formula, so I presume this has something to do with environments. Could anybody give me a hint on this?

Using => and <= instead of -> and <- would make things easier, although the precedence would be different.

..., F), rep(3, 3)), 3) Then see which are TRUE: which(myvec) [1] 4 5 6 13 14 15 22 23 24 I'd like to avoid creating the whole vector if possible; for very large ones it can be time consuming. There should be a way to only create the proper indexes...

Thanks Adrian and Thierry (from the previous answer). I was aware of the all.equal function, but there is nothing similar for <= (e.g. all.smallerEqual)? cheers, jo On 05 Apr 2016, at 14:31, Adrian Du?a <dusa.adrian at unibuc.ro<mailto:dusa.adrian at unibuc.ro>> wrote: Yes, that does have to do with floating point representation.
