Corner case in @formula parsing

2

``` julia> @formula(return ~ dkr + eps + nentinc + salary) ERROR: LoadError: ArgumentError: expected formula separator ~, got return ``` (real life case from Wooldridge 7e)

Are there plans to add DataAPI.jl metadata support in Parquet.jl?

`modularity` function should extend `LightGraphs.modularity`.

* defining metadata for hypergraphs constructed from a matrix (and possibly optionally passing it during construction) * `eltype` for `BipartiteView` (possibly also other, but I have not checked) * `isdirected`...

filter! does not work on NamedArrays

1

Only `filter` works. The printed error is: ``` ERROR: MethodError: no method matching deleteat!(::NamedArrays.NamedArray{Int64,1,Array{Int64,1},Tuple{OrderedCollections.OrderedDict{Int64,Int64}}}, ::UnitRange{Int64}) ```

Type stability of NamedArrays

27

When working on https://github.com/nalimilan/FreqTables.jl/pull/19 we hit a problem of type inference of `NamedArrays`. Would it be possible to fix it? Inference fails even the simplest constructor: ``` julia> @code_warntype NamedArray([1,2,3])...

pager seems not to cache things properly for large tables

11

Steps to reproduce: ``` pager(rand(10^6, 10)) ``` and it takes 30 seconds to display. I am not sure if something can be done to fix it, but ideally large tables...

add an option to have custom recipes to pager

3

This is a general request but what I specifically mean is that if e.g. you do: ``` DataFrame(rand(100, 100), :auto) |> pager ``` that it would be possible that recipe...

Consequence of bug in to_index in Base

We have the following super bad behavior: ``` julia> [1, 2, 3, 4][Not(Not([1.5]))] 1-element Vector{Int64}: 2 julia> [1, 2, 3, 4][Not(Not([1.5]))] 1-element Vector{Int64}: 0 julia> [1, 2, 3, 4][Not(Not([1.5]))] 1-element...
