Hi, Is it possible to sort the rows within a data frame, with respect to the values in one or more of the columns? For example, if I had measured water temperatures at differenrt depths within a lake, on different sampling dates and had a dataframe containing sampling dates (x), sampling depths (y) and data for each day-depth combination (z), would it be possible to rearrange the data frame so that it is sorted by day and then by depth? Best wishes Steve Thackeray
