I note that PooledArray
works just fine, thus I used this workaround (which is sufficient for my current use case) to first convert to String[] and then to PooledArray
df[!,i] = DataFrames.PooledArrays.PooledArray(convert(Vector{String},df[!, i]))
categorical!(df) seems to be an outdated function.
I get a StackOverflowError for this MWE (Windows, Julia 1.4)
