Modular functions for the population simulator for initializing, calculating and collecting simulator results.
population_results(
replicates,
time_steps,
coordinates,
initial_abundance,
results_selection = NULL,
result_stages = NULL
)List of result functions:
initialize_attributes = function())Constructs and returns an initialized nested list for the selected result attributes.
initialize_replicate = function(results)Initializes and returns nested result attributes at the start of each replicate.
calculate_at_timestep = function(r, tm, stage_abundance, harvested, results)Appends and calculates (non-NULL) results and returns nested result attributes at the end of each time step (tm) within replicate (r).
finalize_attributes = function(results)Finalizes result calculations at the end of the simulation.
Number of replicate simulation runs.
Number of simulation time steps.
Data frame (or matrix) of X-Y population coordinates.
Matrix of initial abundances at each stage (in rows) for each population (in columns).
List of results selection from: "abundance" (default), "ema", "extirpation", "extinction_location", "harvested", "occupancy"; "summarize" (default) or "replicate".
Array of booleans or numeric (0, 1, 2, ...) for each stage to indicate which stages are included/combined (each unique digit > 0; optionally named) in the results (default is 1 for all stages).
