Note that DataFrames used to convert columns to `DataArray` automatically in versions before 0.11, so make you don’t use old versions. In particular, remove DataTables or DataFrames will remain stuck at 0.10.1. See [How to upgrade from DataFrames 0.10.1 to 0.11.3?](https://discourse.julialang.org/t/how-to-upgrade-from-dataframes-0-10-1-to-0-11-3/8243/)
