I found this link: [Is there a way that I can attach string labels to integer values in CategoricalArrays?](https://discourse.julialang.org/t/is-there-a-way-that-i-can-attach-string-labels-to-integer-values-in-categoricalarrays/8970)  
Is there anything else that can be done using categoricalarray besides

```julia
julia> a = categorical([1,2,1,3])

julia> recode(a, 1=>"a", 2=>"b", 3=>"c")

```

Thank you.
