Ranking

There are many methods or strategies that you can use to rank your climate or observational data. In all of the many applications I have written over the years it seems I have always use the dense ranking method, I don’t know why I just always have. It’s described in this page I’ve copied from Wikipedia, which lists five of the most popular methods of ranking. Apologies to Ian Rankin for the gratuitous use of his photograph to brighten up this blog with, it was either that or a picture of Althea and Donna from 1977.
