[R] approx with ties = 'ordered'

[Vadim Ogranovich]

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

->  approx(c(1,1), seq(2), 1, method = "const", rule = 2, f = 1, yleft = NA, ties
= "ordered")$y
[1] 2
->  approx(c(1,1), seq(2), 1, method = "const", rule = 2, f = 0, yleft = NA, ties
= "ordered")$y
[1] 2
