eltype not type stable

2

Currently (Julia 0.6) `eltype` on `table` with undefined column names returns a `Tuple` and `eltype` for defined column names is `NamedTuple`. Maybe it could be unified for `NamedTuple` always. This...

Maybe for FisherExactTest we could also allow passing a 2x2 matrix as an argument? (now 4 positional arguments are required) See https://stackoverflow.com/questions/72484655/julia-contingency-table-and-fishers-exact-test-with-dataframes

Performance evaluation features

1

@lindahua, I would recommend adding the following features to _Performance evaluation_ package: **High-level**: 1. Calculation of AUC (exact and approximated at subset of threshold values) 2. Statistical comparison of difference...

Propose some changes to DataFrames.jl API

4

I will comment on the rationale of the changes inline (as I might not understand all the details of the intended design).

add Tables.table(::KeyedArray) method

1

You have now a method defined only for type, but a method for value produces a wrong result due to a default method in Tables.jl for matrices.

http://jsonlines.org/ support

1

I encounter http://jsonlines.org/ more and more often recently. Maybe we can also add a function to read in the data in this format?

Here is the test code: ``` using JSONTables, DataFrames results = DataFrame(cols=Int[], rows=Int[], arraytable=Float64[], objecttable=Float64[]) for cols in (100, 200, 300, 400, 500), rows in (10^3, 10^4, 10^5) @show (cols,...

Add `isless` variant where `missing` is smallest

10

The definitions to make `missing` smallest would be ``` isless2(::Missing, ::Missing) = false isless2(::Missing, ::Any) = true isless2(::Any, ::Missing) = false isless2(x, y) = isless(x, y) ``` @nalimilan - the...

add @? macro

13

I think it is high time to make a bold decision and add `@?` to Missings.jl. The proposal is slightly modified original @tkf code. @pdeffebach + @jkrumbiegel I was not...

parse with Missing

23

I would like to put under consideration if we want to add methods to `parse` that accept `Union{T, Missing}` argument (or create a similar method). This would be something like...
