Generate a New Variable with Rank Starting from the End of Another Var

[Ahmad Ibrahim]

Hi,

I have a dataset that looks at fishing and farming households and ranks them into groups based on some parameters. I am looking to develop a new variable that starts from one digit after the last digit of another variable. For example -

30 30
31 31
32 32
33 33
34 34
end

In this data, I have final_rank and rank_within_group. What I want is for rank_within_group to start from the end point of final_rank. So for example, when final_rank == 1, rank_within_group == 35 (given final_rank == 34 is the last example in this dataset). Any ideas how I might do this?

Thank you!
