Dear List,
I am looking to calculate two things from my data frame and was after some advice. For the example below i want to know.
1. How many unique Orders/Families and Genera there are per eco-name
2. How many incidences are there for each Order/Family and Genus there are per eco-region
I have 650 econame.
I.e for Biak-Numfoor rain forests there are 2 orders, 2 families and two genera. Also, Alismatales are represented once, Asparagales once etc etc.
Thanks for any advice.
Chris
