subset not defined

[etnite]

Hello,

I was just using DataFramesMeta and noticed that @subset is having some issues. Trying out one of the examples from the @subset documentation:

julia> using DataFrames, DataFramesMeta

julia> d = DataFrame(a = [1, 2, missing], b = ["x", "y", missing]);

julia> @subset(d, :a .== 1)
ERROR: LoadError: UndefVarError: subset not defined
Stacktrace:

I haven't tested extensively, but other macros appear to work fine:

julia> @select(d, :a)
3×1 DataFrame
 Row │ a       
     │ Int64?  
─────┼─────────
   1 │       1
   2 │       2
   3 │ missing

What is the status of your DataFrames? I'm guessing it's pre-1.0, which I mistakenly allow for after the addition of the @subset macro.

I will fix this and tag a new version tonight.

You are correct - I didn't realize my DataFrames package was being held back - it is indeed pre v1.0. I will try to resolve dependencies to update it. In the meantime, thank you for the fix.
