combined_iso

Stable isotope data (\(\delta^{13}\)C and
\(\delta ^{15}\)N) for lake trout collected from two ecoregions in
Lake Ontario. Values of \(\delta ^{13}\)C and
\(\delta ^{15}\)N for a benthic baseline (amphipods; baseline 1;
<code>d13c_b1</code> and <code>d15n_b1</code>) and pelagic baseline
(dreissenids; baseline 2; <code>d13c_b2</code> and <code>d15n_b2</code>) with the means for each
baseline calculated (<code>c1</code>, <code>n1</code>, <code>c2</code>, and <code>n2</code>).

Bayesian trophic position models using 'stan' by leveraging 'brms' for
stable isotope data. Trophic position models are derived by using
equations from
Post (2002) <doi:10.1890/0012-9658(2002)083[0703:USITET]2.0.CO;2>,
