Input Data Must Be Numeric????

Hi, and welcome!

Please see the FAQ: What's a reproducible example (`reprex`) and how do I do one? Using a reprex, complete with representative data will attract quicker and more answers.

I also suggest that you repost this as a new topic. A reprex isn't needed, because this isn't yet a coding question. It would help if you would confirm that

  1. All your variables are character
  2. They can be referred to as
  • islands
  • order
  • family
  • species
  • gender

and an idea of how many records you will be using and the form in which the data is now.
