I don't think pretty() should ever return -1 1 or -2 2. It should always return multiples of some round number, so it would have to include 0. But I don't see why it is expanding the range. It doesn't do that when the results are non-negative, e.g. > pretty(0:1, n=1) [1] 0 1 > pretty(0:2, n=1) [1] 0 2 > With n=0, the result is the same, while with n=2 everything is as > documented. > > This behavior nastily messed up some of my cube plots. Is there any chance > that this can be fixed? The documentation has been sitting for 8 years with "FIXME" notes in it, so I wouldn't hold my breath.
