I hope you can help with this one. I have two matricies:
1. A species abundance matrix: <http://r.789695.n4.nabble.com/file/n4643979/2species_matrix.jpg> 2. A species trait score matrix: <http://r.789695.n4.nabble.com/file/n4643979/2trait_matrix.jpg> The trait matrix lists trait scores for each species as listed in the species abundance matrix. I would like to create a script that would effectively count the unique traits (trait richness) for each site and produce an output like this: <http://r.789695.n4.nabble.com/file/n4643979/trait_richness.jpg> Firstly, is this possible in R? Secondly, if so, how would you go about writing a script to achieve my aim? Many thanks in advance, please let me know if you need further information.
