This is an R-package for performing Genetic And Isotopic Assignment using Habitat features.
Most of the package has been written by Eric C. Anderson. The
methodology for assigning individuals using stable isotope was first
written by Hannah Vander Zanden and colleagues. It was reimplemented
here and is now efficient enough to do leave one out cross validation,
etc. These parts of the code are in the file
R/vander-zanden-appendix.R.
To install the development version from GitHub with the
devtools package, you can:
devtools::install_github("eriqande/gaiah")In lieu of a vignette, we provide the full source code for our use of
the gaiah package for a recent paper. See below.
If you want to reproduce all the results from the paper “Genetic
assignment with isotopes and habitat suitability (GAIAH), a migratory
bird case study” in Methods in Ecology and Evolution you will
have to get the gaiah package and then also clone the
analysis repository from https://github.com/eriqande/gaiah-wiwa and then follow
the instructions in that
repository’s README.
