species_define: Define a species

In diazrenata/birdsize: Estimate Avian Body Size Distributions

Define a species

Description

Creates a list with taxonomic/identifying information and parameters for mean and standard deviation of body mass.

Usage

species_define(
  AOU = NA_integer_,
  scientific_name = NA_character_,
  mean_size = NA_real_,
  sd_size = NA_real_,
  sim_species_id = 1
)

Arguments

AOU	the numeric AOU code used for this species in the Breeding Bird Survey
scientific_name	the species' scientific name, as "Genus species"
mean_size	mean body size
sd_size	sd of body size
sim_species_id	identifier; if using taxonomic info, defaults to AOU. If not, defaults to 1. Supplying other values can be useful for simulation models.

Details

The identifying information used depends on which parameters are provided, with the following order of preference: AOU > scientific name > user provided mean and sd > user provided mean and estimated sd.

Value

list with species parameter information

Examples

species_define(AOU = 2881)
species_define(scientific_name = "Perdix perdix")
species_define(mean_size = 400, sd_size = 30)
species_define(mean_size = 400)
