Stable Isotope Analysis in R

This package takes data on organism isotopes and fits a Bayesian model to their dietary habits based upon a Gaussian likelihood with a mixture dirichlet-distributed prior on the mean. It also includes SiBER metrics. See siardemo() for an example. Version 4.1.2 contains bug fixes to allow more than isotope numbers other than 2. Version 4.2 fixes a bug that stopped siar working on 64-bit systems
