community_generate: Simulate individual measurements for many populations

In diazrenata/birdsize: Estimate Avian Body Size Distributions

Simulate individual measurements for many populations

Description

For a community (i.e. a collection of populations of different species, or of the same species at different points in time or locations, etc), simulate individual-level size and metabolic rate measurements.

Usage

community_generate(
  community_data_table,
  abundance_column_name = "speciestotal"
)

Arguments

community_data_table	dataframe containing at least one of AOU, scientific_name, or mean_size and a column for species abundances
abundance_column_name	character, the name of the column with species abundances. Defaults to "speciestotal".

Value

a dataframe one row per individual, all columns from community_data_table, and additional columns for species attributes.

Specifically:

• AOU: the AOU, if provided

• sim_species_id: the sim_species_id if provided

• genus: the genus associated with the AOU if provided, or the genus if provided

• species: the species associated with the AOU if provided, or the species if provided

• individual_mass: the simulated body mass (in grams) for this individual

• individual_bmr: the simulated basal metabolic rate for this individual

• mean_size: the mean body mass for this species (i.e. the parameter used for simulation)

• sd_size: the standard deviation of body mass for this species (i.e. the parameter used for simulation)

• abundance: the number of individuals simulated of this species (i.e. parameter used for simulation)

• sd_method: the method for finding the standard deviation for body mass for this species

• scientific_name: the scientific name

Examples

demo_community <- community_generate(demo_route_clean)
head(demo_community)
