Ricker model of discrete population growth with a carrying capacity

## Usage

run_ricker_model(N0 = 1, params = c(rd = 1.1, K = 100), time = 100)

## Arguments

N0

initial population size of population

params

a vector of carrying capacity (K) and discrete growth rate (rd)

time

Number of time steps over which to project the model

## Value

A data frame with columns time and Nt

run_discrete_logistic_model() and run_beverton_holt_model() for other discrete-time models of population growth with population regulation, and run_logistic_model() for a continuous time model of logistic growth. Also see plot_discrete_population_growth() and plot_discrete_population_cobweb() for plotting trajectory over time and cobweb plots.

## Examples

run_ricker_model(N0 = 1, params = c(K = 100, rd = 1.1), time = 10)
