This function sets up default parameters for a fleet module, including natural log of catchability coefficients (log_q) and fishing mortality (log_Fmort) for fleets. For fishing fleets, log_q is set to an estimation type of "constant" with a default value of 0, while log_Fmort is set to "fixed_effects". For survey fleets, log_q is set to "fixed_effects" and log_Fmort is set to "constant" with a default value of -200.
Arguments
- data
A
FIMSFrameobject returned from runningFIMSFrame()on your long input data.- fleet
A character. Name of the fleet.
Value
A tibble containing the default fleet parameters. See setup_default_parameters
for full column descriptions.
Details
The function builds module-specific defaults by calling helper functions for data, fleet, selectivity, recruitment, maturity, growth, and population components, then combines those defaults into one tibble. You can modify the returned tibble before fitting a model (for example, updating maturity and selectivity parameter values).
To create the default initial numbers at age, this function uses the defaults
from setup_default_Population() and setup_default_Recruitment(), which
are passed to setup_default_init_naa() to calculate initial numbers at age.
Examples
if (FALSE) { # \dontrun{
default_fleet_parameters <- setup_default_Fleet(
data = FIMSFrame(data_big),
fleet = "fleet1"
)
} # }
