There was some discussion <https://github.com/JuliaStats/DataFrames.jl/issues/187> about indexes on Github, but it didn't really get anywhere. I'm also not comfortable with that decision to not have indexes. It makes the dataframes asymmetric, whereas Pandas' and R's are "matrices with named axes".
