RickerRDD: Ricker function to calculate density-dependent reproduction rate

Description

Takes the density-independent rates \(R_p\) of egg production and returns reduced, density-dependent rates \(R\) given as $$R = R_p \exp{- b R_p}$$

Usage

RickerRDD(rdi, species_params, ...)

Arguments

rdi

Vector of density-independent reproduction rates \(R_p\) for all species.

species_params

A species parameter dataframe. Must contain a column ricker_b holding the coefficient b.

...

Unused

Value

Vector of density-dependent reproduction rates.
