Have option to return a Series if there's only one column

Series if single column
Why is returning aseries only possible with one column?

Could there not be a series with more than one parameter/column?

[wesm]

No, that is a DataFrame

[timmie]

Ah, I see. I need still to throgh the timeseries legacy away.

But can I convert frequencies of dataframes as well?

Anyway, I could see some usabilty imporvements in the parsers. I will provide feedback as I go along.

Yes, DataFrames have a resample method too
