'count(func,itr)' is missing

[GlenHertz]

Hi,

In Julia 0.1 we could use 'countp(func, itr)' but in 0.2-pre it gives a warning that it is deprecated and we should use 'count' instead. However, 'count' dosen't exist in 0.2-pre. Is there another function we should use. If so, deprecated.jl should be updated with accurate info.

Thanks,

Glen

I like count(func,itr) just fine. @StefanKarpinski @ViralBShah what do you think?

I've actually wondered where this function went as well. It's still in the
docs anyhow. I find it handy, particularly doing some stats related stuff
with DataFrames.

count(itr) → Integerhttp:https://docs.julialang.org/en/latest/stdlib/base.html#Base.count

Count the number of boolean elements in itr which are true.
countp(p, itr) →
Integerhttp:https://docs.julialang.org/en/latest/stdlib/base.html#Base.countp

Count the number of elements in itr for which predicate p is true.

Why isn't this just sum?

Oh yes, I thought we might have renamed it to something, and that's it.

[JeffBezanson]

Although in the current system count runs faster due to being specialized for summing Ints.

I don't understand why you reintroduced count – it does the same thing as sum.
