metasim_base {metafolio} | R Documentation |
This is an Rcpp implementation of the main simulation. It
is meant to be called by meta_sim
.
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)
n_t |
The number of years. |
n_pop |
Number of populations |
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
|
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? |
