Updates for 1.0

Well, this is as far as I got for 1.0 compat here. The reducedim.jl and broadcast.jl changes are way more involved.

Julia v0.7 compatibility

9

Hi, trying to install this on julia v0.7 and getting lot of warnings + errors. Last commit might address this, is it possible to tag a relase and update uncurated.jl?...

Division DataArray{Int} / Int results in Array{Any}

2

I have come over a problem that depends on whether DataFrames decides that my column is of type `Array{Union{Int64, Missings.Missing},1}` or `DataArrays.DataArray{Int64,1}`. Dividing such arrays by an `Int` results in...

```julia julia> using DataArrays julia> da = @data [1 2; NA 4] 2×2 DataArrays.DataArray{Int64,2}: 1 2 NA 4 julia> mask = @data [true false; false true] 2×2 DataArrays.DataArray{Bool,2}: true false...

We [currently make a copy](https://github.com/JuliaStats/DataArrays.jl/blob/8a7003b4ea9764638b3b7e2b85305d7e4ca1b8ac/src/dataarray.jl#L44-L46) of an `Array{Union{T, Null}}` input to an `Array{T}` because the `data` field of `DataArray` should be `Array{T}`. We should use low-level Julia API once available...

Weighted mean broken for matrices

1

I am on julia 0.6. Currently the following results in a stack overflow: ```julia x = @data [1.0 2.0 3.0] w = Weights(rand(3)) mean(x,w,skipna=true) ``` because this code https://github.com/JuliaStats/DataArrays.jl/blob/8b9e89617ca3539440a9a1b2fc75fc44f86ec850/src/reduce.jl#L178-L185 seems...

`mapreduce_seq_impl()` does not exist in Base for a long time (https://github.com/JuliaLang/julia/pull/16217), but this went unnoticed because since that code path is only used in very special conditions. Another consequence of...

Missing DataArray{T}(dims) constructors

1

We should add `DataArray{T}(dims)` and `DataArray{T}(dims...)` constructors, and similar `DataVector` and `DataMatrix` constructors, for consistency with Base. And possibly deprecate the old `DataArray(T, dims)` constructors. Noticed at https://github.com/JuliaStats/DataFramesMeta.jl/pull/73#discussion_r125589722.

Cannot JSON convert data arrays with NA

3

cannot JSON convert any data arrays with NA. JSON.json(@data [1,2,NA]) used to produce "[1,2,{}]" but now produces the error "Cannot serialize type DataArrays.NAtype" guessing this is because the vector syntax...

Broadcasted not (.!) giving inconsistent return type when DataArray in expression

14

The broadcasted not operator `.!` (new in 0.6) is returning results with unexpected type when used directly on expressions containing a `DataArray`, e.g. ```julia isa(.!isna.(x), DataArray) == true ``` whereas,...
