Method error with RCall 0.9 and DataFrames 0.11.3

Trying to convert a data frame containing a PooledDataArray to R results in a MethodError

Try updating DataArrays. The new version of DataArrays has deprecated PooledDataArray.

I tried updating to the master on RCall and DataArrays, but the same thing is happening julia> Pkg.status("RCall") - RCall 0.9.0+ master julia> Pkg.status("DataArrays") - DataArrays 0.7.0 master julia> Pkg.status("DataFrames") - DataFrames 0.11.3

You should use CategoricalArrays.jl instead of PooledDataArrays.
