In danStich/anadrofish: Anadromous Fish Population Responses to Habitat Changes

# Example usage
\dontrun{
  
# Run Beverton-Holt model to predict number
# of age-0 recruits in freshwater under 
# varying habitat amount with 100 fish and
# default parameter settings.
  
# Start by making a sequence of habitat amounts (acres)
  acres = seq(0, 100, 1)
  
# Run the Beverton-Holt curve for 100 individuals
# in varying habitats with default a and b parameters
  recruits = beverton_holt(S=100, acres = seq(0,1000,10))
  
# Plot the results
  plot(x = acres, y = recruits, type='l')
