RI index is calculated wrongly I think about ethnobotanyr HOT 4 CLOSED

Thank you for the useful comment.
Nice that you made the test and the suggestion.

This was a bug in both the RIs and the RFCs code.

Cool, thanks. I will let you know if I catch anything else. I am not going though everything, just calculating some of the indices "by hand" for teaching purposes - and if they don't produce the same results I'll notice. I will send you the materials when they are done.

Thank you for a very quick fix. I think I was a little quick:
The mutate should of course be dplyr::mutate, to avoid mistakes.

Also, RFCs worked as it should already. the "fix" introduced an error. It should be divided by "N" (all interviewees), not by max(FC). RFCs(max) and RFCs are not that related, which is a bit confusing from the paper.

I think I managed to catch the bugs now. Please let me know if you find anything else. CRAN is on vacation now but I will try to get the latest working code on the CRAN after January 4th (when they are back). Hope this works in time for your course.
Please share any course materials etc. Would be nice to see how this is being taught.
