init_closure: Initialise spatial closure(s)

init_closureR Documentation

Initialise spatial closure(s)

Description

init_closure sets up the parameters for spatial closure(s) in the simulation.

Usage

init_closure(
  input_coords = NULL,
  basis = "commercial",
  rationale = "high_pop",
  spp1 = "spp1",
  spp2,
  year_start = 1,
  year_basis = NULL,
  closure_thresh = 0.95,
  sc = 1,
  temp_dyn = "yearly"
)

Arguments

input_coords

is a dataframe of x,y coordinates defining the closure(s). If the temp_dyn are not static, the list should be multilayered with the [[week/month]][x, y]

basis

is a character string detailing the data used to define a closure 'on the fly'. Can be survey to be based on survey data, commercial to be based on commercial data, real_pop to be based on the simulated population. Not needed if coordinates defined.

rationale

is the basis for any 'on the fly' closure. Can be high_pop for the areas of a highest population or high_ratio for the areas of the highest ratio of population 1: population 2. Not needed if coordinates defined.

spp1

is the first population as basis for the closure. If rationale = high_pop then that should go here If rationale = high_ratio, its the target (high quota) population. Not needed if coordinates are defined.

spp2

is the second population when rationale = high_ratio, the lowest quota population. Not needed if coordinates provided or rationale = high_pop.

year_start

is a Numeric indicating the first year the spatial closure(s) shoud be implemented.

year_basis

is a vector indicating the years of data the closure is based on...Must be before year_start. If NULL then closure will be calculated dynamically each year.

closure_thresh

is the quantile of catches or high catch ratio which determines closed cells

sc

is a Numeric indicating the scale of data to use for the closure, e.g. if the data is aggregated to 2 x 2 cells, is 2.

temp_dyn

is a character string detailing whether closures should be temporally 'annual', or change 'monthly' or 'weekly'.

Value

is a list of parameter settings for the spatial closures which serves as an input to run_sim.
