Dear R community, I wish to ask a short question concerning factor-data
in dataframes: When I subset the data and get rid of all data for one level,
I still retain the level name (obtained by levels(dataframe$variablename) ).
Is there a convenient way to get rid of the levels for which all data has
been deleted?
Thank you and wishing you an excellent day!
Georg.
