Script to count unique values from two linked matricies

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.

Hi

I have no access to Nabble so it is difficult to understand what do you want.
Why not, everything is possible with R. Maybe you could provide data by dput(species).

Maybe you want something like ?table or ?aggregate.

Without data it is hard to say.
