Stable Isotope Bayesian Ellipses in R

Fits bi-variate ellipses to stable isotope data using Bayesian inference with the aim being to describe and compare their isotopic niche.



  • To be implemented...

SIBER 2.0.3

  • Added a new vignette illustrating how to add custom ellipses to each group manually

SIBER 2.0.2

  • Bug in Group labels as character strings fixed
  • Community labels as character strings now implemented

SIBER 2.0.1

  • Group labels can now be strings and do not have to be sequential integers (#14)


  • Fitting is now via JAGS
  • Data are z-score transformed prior to fitting to improve convergence
  • Data structures have now changed from previous versions embedded within SIAR so you will have to reformat your data and write new scripts to interface with the new code
