# Ricker model of discrete population growth with a carrying capacity

`run_ricker_model.Rd`

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
