WARNING: using Bootstrap.data in module Main conflicts with an existing identifier about bootstrap.jl

[juliangehring]

What module is causing the conflict? I can't reproduce the warning with a recent julia 0.5.0-dev+5179 version. Can you post a reproducible example?

[juliangehring]

I also can't get the warning with julia v0.5.0-rc2. I guess that is what you were referring to with "julia 0.5 release"?

Hmm... I didn't check before, but this is only happening when using the Juno IDE in the Atom editor. In my file, I execute:

using DataFrames,
      Bootstrap

And don't get the warning. Then:

function getbootstrap(v, n=1000, i=0.95)
    bs = bootstrap(v, mean, BasicSampling(n))
    ci1 = ci(bs, BasicConfInt(i))
    return ci1[1]
end

And this spits the warning:

WARNING: Method definition getbootstrap(Any) in module Main at /Users/KBLaptop/computation/Science/gender-comp-bio/src/bootstrapping.jl:6 overwritten at /Users/KBLaptop/computation/Science/gender-comp-bio/src/bootstrapping.jl:6.

But I just opened the REPL and did the same thing, but did not get a warning. So this might be a problem with Juno - I'll open an issue over there.

Julia Version 0.5.0-rc2+0, what you get when you do git checkout release-0.5

Ok, thank you for the example. When does the WARNING: using Bootstrap.data in module Main conflicts with an existing identifier occur? The warning in your example seems to be a different one.

[kescobo]

Ahh, excellent point. I cannot now reproduce that original warning and the associated errors :-/

It was happening when I was including a script that had the above function definition, and then using it on some DataFrame columns, but I just went back and repeated the procedure and only see the method definition warning. I'll let you know if it pops up again, but I can't seem to find it...

[juliangehring]

No worries - let me know in case it shows up again.

[kescobo]

Will do!
