summariseIsotopeData

A wrapper of plyr:ddply to summarise a data frame.

Estimates the trophic position of a consumer relative
to a baseline species. It implements a Bayesian approach which combines an
interface to the 'JAGS' MCMC library of 'rjags' and stable isotopes. Users are
encouraged to test the package and send bugs and/or errors to
trophicposition-support@googlegroups.com.

summariseIsotopeData function

<dl><dt>df</dt>
<dd>a data frame that contains the isotope values. It needs to have the
following columns: d13C, d15N, Species and FG. Species stands for the
scientific name (or common name), and FG stands for the functional group
for each species. If the data frame does not have Species and FG columns,
it will raise an error. If the columns change their names, they need to be
stated as well in the grouping variable.</dd>
<dt>grouping</dt>
<dd>a vector with the name of the columns (variables) that will
be used to summarize, and plot the data frame.</dd>
<dt>printSummary</dt>
<dd>logical value indicating whether the summary is printed.</dd>
<dt>...</dt>
<dd>optional arguments that are passed to the function for later use.</dd></dl>

Arguments

Function that summarises a data frame containing stable isotope values (d13C
and d15N) grouping by Species and FG columns — summariseIsotopeData
