savesources: savesources

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

Description

Convenience function to save simulated prey source isotope parameters in format that can be used by 'MixSIAR'. Can either write the data to a .csv file and/or return as a dataframe object. Can be called independently if mean and standard deviation of the prey source isotope distributions are known (e.g., if simulating that prey source isotope disrtibutions are known perfectly) or can be called from 'samplesources' to save simulated sampling of prey source isotope values.

Usage

savesources(
  food,
  filename = NULL,
  mu_carb,
  sd_carb,
  mu_nit,
  sd_nit,
  popsize,
  writefile = T,
  returnobject = F
)

Arguments

food	list object of simulated food sources
filename	name of file to save
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
popsize	vector whose length = 'num_sources', each entry of which is the size of the diet source population to simulate
writefile	boolean, whether to write the csv to file needed by MixSIAR default is TRUE
returnobject	boolean, whether to return an object within the current environment, default is FALSE

Value

either writes a MixSIAR formatted csv to file or a dataframe object
