The R packagezoolog includes functions andreference data to generate and manipulate log-ratios (also known as logsize index (LSI) values) from measurements obtained on zooarchaeologicalmaterial. Log ratios are used to compare the relative (rather than theabsolute) dimensions of animals from archaeological contexts (Meadow1999, ISBN: 9783896463883).zoolog is alsoable to seamlessly integrate data and references with heterogeneousnomenclature, which is internally managed by azoologthesaurus. A preliminary version of the zoolog methods was first used byTrentacoste, Nieto-Espinet, and Valenzuela-Lamas (2018)https://doi.org/10.1371/journal.pone.0208109.

You can install the released version of zoolog fromCRAN with:
install.packages("zoolog")And the development version fromGitHub with:
install.packages("devtools")devtools::install_github("josempozo/zoolog@HEAD",build_vignettes =TRUE)Several fellow colleagues helped building the Thesaurus and testedthe code, increasing its robustness: Moussab Albesso, Canan Cakirlar,Jwana Chahoud, Jacopo De Grossi, Dimitrios Filioglou, Armelle Gardeisen,Sierra Harding, Pilar Iborra, Michael MacKinnon, Nimrod Marom, ClaudiaMinniti, Francesca Slim, Barbara Stopp, and Emmanuelle Vila. We aregrateful to them for their comments and help.
We are particularly grateful to Sabine Deschler-Erb and BarbaraStopp, from the University of Basel (Switzerland) for making thereference values of several specimens available through the ICAZ RomanPeriod Working Group, which have been included here with theirpermission. We also thank Francesca Slim and Dimitris Filioglou from theUniversity of Groningen, Claudia Minniti from University of Salento,Sierra Harding and Nimrod Marom from the University of Haifa, CarlyAmeen and Helene Benkert from the University of Exeter, and MikolajLisowski from the University of York for providing additional referencesets. Allowen Evin (CNRS-ISEM Montpellier) saw potential pitfalls in theuse of Davis’ references for sheep, which have been now solved.
