Take the maximum of every 12 columns
Thank you for your kind replies. Maybe I was not clear with my question (I
apologize) or I did not understand...
I would like to take the max for X0...X11 and X12...X24 in my dataset. When
I use pmax with the function byapply as in
byapply(df, 12, pmax)
I get back a list which I cannot convert to a dataframe. Am I missing
something? Thanks again!
Sincerely,
Milu
