Hi all, I am using DataFrames to import couple of hundreds of DataFiles, that get merged into one single DataFrame. Currently I am wondering about what would be the best way to initialize that DataFrame, and hope you can help me.
If I do something like df_all = DataFrame() for file in filelist df_tmp = readtable(file) ... do stuff to the df_tmp... append!(df_all,df_tmp) end I obviously can't match the column numbers, and everything fails. I wold need to initialize the DataFrame using sth like df_all = DataFrame(:col1 = Float64[], :col2 = Int64[]) but I have 26 columns, and from experiment to experiment they tend to change. Useful is setting up a Dictionary, that relates Columns to Eltypes, but there is currently no way of supplying that to the initialization process. Is there something I missed? Or could easier initialization routines be implemented? Thank you, Max -- You received this message because you are subscribed to the Google Groups "julia-stats" group.
