iteratesourcesamp: iteratesourcesamp

In syanco/checkyourself: Simulates a simple agent-based species distribution model

Description

Function to run entire trophic iso-ecology simulation iterating across sample sizes for sample-based estimation of prey source isotopic distribution estimation. Requires the designation of a folder for all data output. Calls all necessary functions to run a complete simulation and saves outputs into format ready for analysis with 'MixSIAR'.

Usage

iteratesourcesamp(
  folder,
  num_sources,
  popsize,
  mu_carb,
  sd_carb,
  mu_nit,
  sd_nit,
  sourcesamp,
  num_individ,
  steps,
  diet_prop,
  window
)

Arguments

folder	String, path to folder where simulated data should be saved
num_sources	integer, number of potential food sources to simulate
popsize	vector whose length = 'num_sources', each entry of which is the size of the diet source population to simulate
mu_carb	vector whose length = 'num_sources', each entry of which is the mean 13C value of the diet source population to simulate
sd_carb	vector whose length = 'num_sources', each entry of which is the standard deviation of the 13C of the diet source population to simulate #' @param mu_nit vector whose length = 'num_sources', each entry of which is the mean 15N value of the diet source population to simulate
sd_nit	vector whose length = 'num_sources', each entry of which is the standard deviation of the 15N of the diet source population to simulate
sourcesamp	Vector of sample sizes through which the source sampling walks
num_individ	Integer, the number of individuals to simulate
steps	Integer, the number of time steps to simulate. Passed to 'eatfoodsteps'.
diet_prop	vector, the relative probability of selecting a source. Must have an entry for each source. Passed to 'eatfoodsteps' and then to 'eatfoodonce'.
window	Integer, the consumer isotope integration window representing the number of steps across which prey isotope values are integrated in an individual consumer to generate consumer tissue isotope values. Window must be less than or equal to 'time'.

Value

Writes simulated consumer mixture distribution file, sample-based prey source estimate files for each value of 'sourcesamp', and a trophic discrimination factor file all in format that can be used by 'MixSIAR'.
