A set of concentration dependence values for stable isotope analysis

Description

A dataset of concentration dependent corrections for 4 food sources of brent geese. Intended for use in a Stable Isotope Mixing Model.

Usage

data(concdepdemo)

Format

A 5 column, 4 row data.frame object containing the concentration dependence data for the geese1demo and geese2demo datasets. The first column Source is a factor determining the name of the source. The second and third columns are the mean d13C and mean d15N concentration values for each source respectively. Columns 3 and 5 are the standard deviations but these are not currently implemented in either simmr or MixSIAR stable isotope mixing models. Note that the order of the isotope data has been swapped since siar in order to present d13C as the first isotope and hence on the x-axis by default.
