create_control: Create a control file

In AustralianAntarcticDivision/tagsim: Simple population model for tag-based simulations

Description

The control file specifies the simulation parameters

Usage

create_control(years, regions, pop_pars, rec_pars, harvest_pars, tag_pars,
  fish_pars, move_pars, assess_pars)

Arguments

years	vector of years (integers starting with 1)
regions	vector of regions (integers starting with 1)
pop_pars	list of population parameters containing the initial population size ("initial") and instantaneous natural mortality ("nat_mort")
rec_pars	list of recruitment parameters containing the name of the mechanism for calculating recruitment ("type"; can be either "constant", "logistic", "bevholt" or "ricker") and ("variation"; can be "stochastic" or "none") Currently the resilience is steepness (for TOA=0.75 and for TOP=0.7), rk and K is carrying capacity and rk is the number of recruits per unit spawner when B = K see est_recruits, the spatial distribution of the recruitment is assigment with "spat_dist" which can be "uniform", "lognormal" or "user" specified (see recruit_area). Recruitment The stochasisity in recruitment is determined
harvest_pars	harvest parameters a list containing "type" ("const_exploit" = constant exploitation rate, "TAC" = constant catch, ...), (see calc_catch)
tag_pars	list of tag related parameters that reflects the simulated tagged population (mort, shed, report)
fish_pars	list of parameters relating to the fishing strategy. The intent is for these to control the spatial dynamics of fishing and for harvest_pars to determine total catch (see fishing_locs)
move_pars	list of movement parameters "type", "prob" (see move_matrix)
assess_pars	list of assessment parameters that includes a seperate set of tagging parameters (see do_assessment)

Details

A simulation is run using the function (see run_sim)
