I try to load this package and get errors.

```julia
julia> using DataArrays

That package is deprecated, as seen here: [https://github.com/JuliaStats/DataArrays.jl](https://github.com/JuliaStats/DataArrays.jl) .  
Missing value support is now in the base language since Julia 1.0, so there’s no need for the DataArrays package.

Maybe you’re looking for DataFrames? [GitHub - JuliaData/DataFrames.jl: In-memory tabular data in Julia](https://github.com/JuliaData/DataFrames.jl)
