Hey! I have a dataset that looks somewhat like this:   EMPLID CURRENT_COLLEGE  1                     ABC 1                     ABC 1                     XYZ 1                     XYZ 2                     CED 2                     VIN 2                     VIN   I have to compare the values for each row in current_college and create a separate column called 'Change' that captures if the college for each ID has changed compared to the first observation. The output table should look something like this:   EMPLID CURRENT_COLLEGE  CHANGE 1                     ABC                          0 1                     ABC                          0 1                     XYZ                           1 1                     XYZ                           1 2                     CED                          0 2                     VIN                            1 2                     VIN                            1   I have been scratching my head over this for hours and I have just started working with SAS! Are there any efficient ways of grouping observations in SAS (like 'group' in dplyr package in R)? Thanks 🙂 ... View more
