In siar: Stable Isotope Analysis in R

Description

This package takes data on animal isotopes and fits a Bayesian model to their dietary habits based upon a Gaussian likelihood with a dirichlet prior mixture on the mean. The main function, siarmcmcdirichletv4(), allows the user to specify the data and choose the size of the MCMC run. A wrapper for the package, siarmenu() gives a walkthrough of all the functions contained in the package and produces some pretty plots. Some example data on Geese plasma is included for illustration.
