print.fb4_result: Print Method for fb4_result Objects

In fb4package: 'Fish Bioenergetics 4.0' Model Implementation with High-Performance 'TMB' Backend

Print Method for fb4_result Objects

Description

Displays a concise summary of an fb4_result object. The output adapts to the fitting method used: traditional methods (binary search, optim, direct) show weight, growth, consumption, and convergence; "mle" shows parameter estimates with confidence intervals and AIC; "bootstrap" shows mean/SD estimates and CI; and "hierarchical" shows population-level parameters with model fit statistics.

Usage

## S3 method for class 'fb4_result'
print(x, ...)

Arguments

x	fb4_result object
...	Additional arguments (not used)

Value

Invisibly returns the input object

Examples

data(fish4_parameters)
sp   <- fish4_parameters[["Oncorhynchus tshawytscha"]]$life_stages$adult
info <- fish4_parameters[["Oncorhynchus tshawytscha"]]$species_info
bio  <- Bioenergetic(
  species_params     = sp,
  species_info       = info,
  environmental_data = list(
    temperature = data.frame(Day = 1:30, Temperature = rep(12, 30))
  ),
  diet_data = list(
    proportions = data.frame(Day = 1:30, Prey1 = 1.0),
    energies    = data.frame(Day = 1:30, Prey1 = 5000),
    prey_names  = "Prey1"
  ),
  simulation_settings = list(initial_weight = 100, duration = 30)
)
bio$species_params$predator$ED_ini <- 5000
bio$species_params$predator$ED_end <- 5500
result <- run_fb4(bio, strategy = "direct", p_value = 0.5, verbose = FALSE)
print(result)
