Hi,
I am a bit surprised how approx resolves ties when ties = 'ordered'. In the
following two examples I'd expect the first expression to return 1 (not 2).
The documentation reads that "that 'f=0' is right-continuous and 'f=1' is
left-continuous" so one would expect the argument to matter when resolving
ties.
Thanks,
Vadim
