Cannot vcat DataFrames with ReadStatTables.LabeledArrays

[greimel]

using ReadStatTables, DataFrames
lbls1 = Dict(1=>"a", 2=>"b");
x = LabeledArray([0, 1, 2], lbls1)

df = DataFrame(; x)

[x; x]
[df; df] # ERROR: MethodError: Cannot `convert` an object of type Int64 to an object of type LabeledValue{Int64, Int64}

I am not sure if that is due to a bug in DataFrames or ReadStatTables, though.

It is a problem with ReadStatTables.jl, because it should define DataAPI.defaultarray method and it does not. The reason is that the eltype LabelledValue needs to be stored in LabelledVector and package should signal this.

Fixed by @junyuan-chen in junyuan-chen/ReadStatTables.jl#28 - thank you so much!
