Generates species abundances based on species response functions and environmental variables.
abundances(env, spp, nc)
env |
Environmental variables. Usually generated by |
spp |
Species parameters. Usually generated by |
nc |
Number of counts to be simulated. If omitted no simulation of the counting process is carried out. |
spp |
