realistic_biotracer_data

This is an artificial and realistic biotracer dataset, more specifically stable isotope analyses,
 made to illustrate the package on a complex dataset. All tables whose name start by "realistic" are
 describing different data from the same trophic groups.

Biotracers and stomach content analyses are combined in a Bayesian hierarchical model
to estimate a probabilistic topology matrix (all trophic link probabilities) and a diet matrix
(all diet proportions).
The package relies on the JAGS software and the 'jagsUI' package to run a Markov chain Monte Carlo
approximation of the different variables.

realistic_biotracer_data function

A table with 300 rows and 3 columns. Each row is an isotopic sample from one individual, and
there are 30 individuals sampled in each trophic group.
The columns are:<dl>
 <dt>group</dt>
<dd>the trophic group the individual belonged to</dd> <dt>d13C</dt>
<dd>the d13C measurement made on that individual</dd> <dt>d15N</dt>
