sim_pop: Operating model

In merrillrudd/LIME: Length-based Integrated Mixed Effects (LIME) assessment method

Description

sim_pop Age-converted-to-length-based operating model specifying true population dynamics

Usage

sim_pop(
  lh,
  Nyears,
  pool,
  Fdynamics,
  Rdynamics,
  Nyears_comp,
  comp_sample,
  init_depl = 0.99,
  seed,
  sample_type = "catch",
  mgt_type = "F",
  fleet_proportions,
  nareas
)

Arguments

lh	list of life history information, from create_lh_list
Nyears	number of years to simulate
pool	if nseasons (in life history list) is greater than one, pool the generated data into annual time steps, or leave at the season-level? FALSE will generate shorter time step life history info, mean length
Fdynamics	Specify name of pattern of fishing mortality dynamics, Constant, Endogenous, Oneway, or None. Input matrix with dimensions fleets = rows, years = columns
Rdynamics	Specify name of pattern of recruitment dynamics, Constant, Pulsed, Pulsed_up, or BH
Nyears_comp	number of years of length composition data
comp_sample	sample size of length composition data annually
init_depl	default=NULL, can specify a starting depletion, initial F (using init_F), or 2 values that indicate range from which to choose them
init_F	default=NULL, can specify a starting F, an initial depletion (using init_depl), or 2 vaues that indicate range from which to choose them
seed	set seed for generating stochastic time series
sample_type	a character vector specifying if the length comps are sampled from the 'catch' (default) or from the population
mgt_type	removals based on F (default) or catch
fleet_proportions	vector specifying the relative size of each fleet in terms of fishing pressure. must have length = nfleets and sum to 1.
nareas	number of areas, default = 1, if greater than 1, must be equal to the number of fleets

Value

named list of attributes of true population/data
