metasim_base: Base-level metapopulation simulation function

In seananderson/metafolio: Metapopulation Simulations for Conserving Salmon Through Portfolio Optimization

Base-level metapopulation simulation function

Description

This is an Rcpp implementation of the main simulation. It is meant to be called by meta_sim.

Usage

metasim_base(
  n_pop,
  n_t,
  spawners_0,
  b,
  epsilon_mat,
  A_params,
  add_straying,
  stray_mat,
  assess_years,
  r_escp_goals,
  sigma_impl,
  add_impl_error,
  decrease_b,
  debug
)

Arguments

n_pop	Number of populations
n_t	The number of years.
spawners_0	A vector of spawner abundances at the start of the simulation. Length of the vector should equal the number of populations.
b	Ricker density-dependent parameter. A vector with one numeric value per population.
epsilon_mat	A matrix of recruitment deviations.
A_params	A matrix of Ricker a parameters
add_straying	Implement straying between populations?
stray_mat	A straying matrix.
assess_years	A vector of years to assess a and b in
r_escp_goals	A matrix of escapement goals.
sigma_impl	Implementation standard deviation for the implementation error beta distribution.
add_impl_error	Add implementation error? Implementation error is derived using impl_error.
decrease_b	A numeric value to decrease all streams by each generation. This is intended to be used to simulate habitat loss, for example though stream flow reduction with climate change.
debug	Boolean. Should some debuging messages be turned on?
