Things we should deprecate for consistency with Base

2

In the interest of having an API consistent with that of Base, I think we should deprecate the following methods: - [ ] `DataArray(T, ...)` in favor of `DataArray{T}(...)` (likewise...

Remove bitenumerate; use itr macro from Iterators instead

Can be merged once JuliaLang/Iterators.jl#33 makes it into a release

Change unique() to return values in the same ordering as levels for PDAs

6

While the generic unique() method says it preserves the order of appearance, the ordering of levels is more likely to be useful. In particular, it will allow StatsModels to use...

@johnmyleswhite maybe it's useful to someone i don't know. This function handles NA. ``` function PearsonCorr(x::DataArray, y::DataArray) Corr = 0.0 Xavg = 0.0 Yavg = 0.0 Xavg2 = 0.0 Yavg2...

reorder(x, y) doesn't work

1

I'm not sure what `reorder(x::PooledDataArray, y::AbstractVector...)` is supposed to do, but it seems to rely on a function that doesn't exist. Better remove it at that point... ``` julia julia>...

Support DateTime math

1

Subtracting two `DataArray{DateTime}` arrays currently doesn't work: ``` julia julia> using DataFrames julia> df = DataFrame() 0x0 DataFrames.DataFrame julia> df[:A] = [DateTime(2015,1,1), DateTime(2015,1,2)] 2-element Array{DateTime,1}: 2015-01-01T00:00:00 2015-01-02T00:00:00 julia> df[:B] =...

Work around undefined values when converting DataArrays?

Should we make the following snippet work? ``` julia> using DataArrays julia> da = data(Array(Any, 8)) 8-element DataArray{Any,1}: #undef #undef #undef #undef #undef #undef #undef #undef julia> da[2:8] = [1,...

hash function is fragile/broken [InexactError]

1

Wondering if the _conversion_ functions/constructors in the [DataArray hash function](https://github.com/JuliaStats/DataArrays.jl/blob/master/src/dataarray.jl#L674) should perhaps be _casts/reinterprets_. Fixing this will also probably fix #146. ``` julia julia> versioninfo() Julia Version 0.4.0-dev+4436 Commit 237cdab...

Hi, I've implemented two functions to reorder the pool and the refs of a PDA object. The functions are similar in the semantic sense with R's `ordered` function. I've tested...
