Is the following really intended behaviour of the ':' operator,
> s <- pi - 3.0 + 1e-07
> x <- s:pi
> x
[1] 0.1415928 1.1415928 2.1415928 3.1415928
though the last entry in the range vector is greater than pi?
> x[4] > pi; x[4] - pi
[1] TRUE
[1] 1e-07
and the same, of course, for the seq() function.
I would understand this behaviour for 1e-14 or so, but it seems
unexpected for such a distinct difference as 1e-07.
