Understood. Will review the docs again. My data is from an external source which, among other things, ensures that it's sorted correctly. I was asking for a way to have ggplot use the ordering in place, instead of re-ordering everything. Apologies if it wasn't clear from the original post.
Anyway, if the data is correctly presorted, unique should work ok, I think. On Aug 15, 2018, 9:23 AM, at 9:23 AM, Bert Gunter <bgunter.4...@gmail.com> wrote: >1.
