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 julia> r = RObject(j1) ERROR: MethodError: no method matching sexp(::Type{RCall.StrSxp}, ::DataArrays.PooledDataArray{String,UInt16,1}) Closest candidates are: sexp(::Type{RCall.StrSxp}, ::Symbol) at /Users/sjbespa/.julia/v0.6/RCall/src/convert/base.jl:217 sexp(::Type{RCall.StrSxp}, ::Ptr{RCall.CharSxp}) at /Users/sjbespa/.julia/v0.6/RCall/src/convert/base.jl:266 sexp(::Type{RCall.StrSxp}, ::AbstractString) at /Users/sjbespa/.julia/v0.6/RCall/src/convert/base.jl:267 ...

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.
