sim_par: Control Values for 'simulate'.

In ianjonsen/simsmolt: simulate Atlantic salmon smolt migration and detections on acoustic arrays

Control Values for simulate.

Description

sim_par defines the simulation parameters & control scenarios used by simulate.

Usage

sim_par(
  move = c("brw", "rw", "drift"),
  temp = TRUE,
  advect = TRUE,
  noise = NULL,
  growth = TRUE,
  shelf = TRUE,
  scenario = "rs",
  land = FALSE,
  boundary = FALSE,
  ...
)

Arguments

move	"brw" a biased RW; "rw" simple RW; "drift" no active swimming
temp	logical
advect	logical
noise	numeric; add small random component to u,v vectors - only applies when mode = "drift"
growth	logical
shelf	logical; should smolts be constrained to stay in water > - 1000 m depth (continental shelf)
land	keep track of sim rep hitting land (TRUE)
boundary	keep track of sim rep hitting sim boundary (TRUE)
...	additional simulation control parameters
migs	migration scenario 1 or 2 (stop migration upon arrival to Grand Banks)

Details

The movement process used predominantly in the simulation is selected by the move argument. Additional parameters include: temp is movement temperature-dependent; advect do ocean currents influence movement; growth do smolts grow in temp-dependent fashion; start.date; start (location); coa centre of attraction (can be NULL); mdir directional bias (a 2-element vector); rho concentration of step directions (for wrapped-Cauchy, a 2-element vector); ...

Value

Returns a list with components

move	the main move process
temp	temperature-dependent movements
advect	ocean-current-dependent movements
noise	add random noise to current u,v values
growth	temperature-dependent growth
shelf	movements constrained to stay on shelf
migs	migration strategy
land	record if smolt gets "stuck" on land, thereby ending simulation
boundary	record if smolt hits simulation boundary, thereby ending simulation
pars	list of additional, required control parameters
