A 3-isotope fake stable isotope mixing data set

Source: R/data.R

A fake data set with 30 observations on 3 isotopes, with 4 sources, and with corrections/trophic enrichment factors (TEFs or TDFs), and concentration dependence means

Format

A list with the following elements

mixtures

A three column matrix containing delta 13C, delta 15N, and delta 34S values respectively

source_names

A character vector of the food source names

tracer_names

A character vector of the tracer names (d13C, d15N, d34S)

source_means

A matrix of source mean values for the tracers in the same order as mixtures above

source_sds

A matrix of source sd values for the tracers in the same order as mixtures above

correction_means

A matrix of TEFs mean values for the tracers in the same order as mixtures above

correction_sds

A matrix of TEFs sd values for the tracers in the same order as mixtures above

concentration_means

A matrix of concentration dependence mean values for the tracers in the same order as mixtures above
