Hello, (Warning. This might not be the most complete or elegant solution ...)
If you want a sorted dataframe: look here for example http://tolstoy.newcastle.edu.au/R/help/05/02/12391.html To convert the factors from a data frame, you have to call as.ordered for each factor separately (not for the dataframe). To convert two factors a and b and merge them into a new dataframe: newFrame <- as.data.frame(cbind(as.ordered(a),as.ordered(b))) l For a larger number of factors this can be done with a loop or better one of the "apply"-functions.
