@Edmund, it is initialized to 1 for any possible value of its argument; for every x , every time a sequence with x in the first slot is encountered, e,g, Sequence[x, y_], the current value of cnt[x] is appended to the sequence (to get {x, y cnt[x]}) and cnt[x] is incremented. ... Is this in any way an answer to your question?

@kglr How does your cnt[#]++ work?

| Jan 15, 2018 at 23:28 | comment | added | ramesh | I think it should work. I will apply it to my data and update you. Thank you so much kglr. You have helped me by answering most of my questions. I owe you more than I can pay! | |

| Jan 15, 2018 at 22:56 | comment | added | ramesh | @ kglr, thank you for your answer. One of the problem of using gatherby (at least for me) is that it rearranges data based on id variable. Is there any way to keep the order of id variable the same. Thank you. | |
