geese_data: Geese stable isotope mixing data set

In simmr: A Stable Isotope Mixing Model

Geese stable isotope mixing data set

Description

A real Geese data set with 251 observations on 2 isotopes, with 4 sources, and with corrections/trophic enrichment factors (TEFs or TDFs), and concentration dependence means. Taken from Inger et al (2016). See link for paper

Usage

Format

A list with the following elements

mixtures
