Reordering columns of a Deedle Frame

Question

Is there a more efficient way to reorder columns in a Deedle frame than doing something like the following:

let fr2 = fr.Columns.[["colC"; "colA"; "colB"]]

It seems a bit inefficient, especially given that I have to iterate through a ton of these files every weekend. There is a related question here but doesn't seem to work for me.

Answer 1

How about this:

let df = Frame.ofColumns(df.Columns.Realign(newcolidx))

As this appears to me returning a new df, it might not be ideal for you.

And this Issue still remains open.
