Here you can find ready to use code material related to my work. I also have a poorly maintained Github account.

Description: Restoration ecologists aim to re-establish diverse, functioning communities. This R package produces a species assemblage (i.e., a species relative abundance distribution) based on a user-defined functional trait profile. The species abundances can converge on specific community-weighted mean trait values and this function can simultaneously maximize functional diversity.
