Get Closed Loop Reference Points

Computes fishery and biological reference points either using "true" simulated values from the operating model or using assessment-derived data and report objects. Supports single-region and multi-region reference points.

Usage

get_closed_loop_reference_points(
  use_true_values,
  sim_env,
  asmt_data = NULL,
  asmt_rep = NULL,
  y,
  sim,
  reference_points_opt = list(n_avg_yrs = 1, SPR_x = 0.4, calc_rec_st_yr = 1, rec_age =
    1, type = "single_region", what = "SPR"),
  n_proj_yrs
)

Arguments

use_true_values

Logical. If TRUE, uses values from the simulation environment (`sim_env`) for calculating reference points. If FALSE, uses `asmt_data` and `asmt_rep`.

sim_env

Simulation environment

asmt_data

Optional list. Assessment data object (from RTMB) if not using true values.

asmt_rep

Optional list. Assessment report object (from RTMB) if not using true values.

y

Integer. Number of years to include in calculations (usually the last year of the assessment or simulation).

sim

Integer. Index of the simulation replicate in `sim_env`.

reference_points_opt

List. Options for reference point calculations:

n_avg_yrs: Number of years to average over demographic rates. Default is 1.
SPR_x: Target SPR fraction for reference point calculations. Default is 0.4.
calc_rec_st_yr: Year to start calculating mean recruitment. Default is 1.
rec_age: Age at recruitment. Default is 1.
type: Reference point type: "single_region" or "multi_region". Default is "single_region".
what: Method for reference point calculation. Options include "SPR", "BH_MSY", "independent_SPR", "independent_BH_MSY", "global_SPR", "global_BH_MSY". Default is "SPR".

n_proj_yrs

Number of projection years

Value

A list with elements:

f_ref_pt: Array of fishing reference points by region and projection year.
b_ref_pt: Array of biological reference points by region and projection year.
virgin_b_ref_pt: Array of unfished biological reference points by region and projection year.
