Several osteometrical references are provided in zoolog to enable researchers to use the one of their choice. The user can also use their own osteometrical reference if preferred.

referencesDatabase
Each reference is a data.frame including 4 columns:
The taxon to which each reference bone belongs.
The skeletal element.
The type of measurement taken on the bone.
The value of the measurement taken on the bone. All the measurements are expressed in millimetres.
Currently, the references include reference values for the main domesticates and their agriotypes (Bos, Ovis, Capra, Sus), and other less frequent species, such as red deer and donkey, drawn from the following publications and resources:
Bos taurus. Female cow dated to the Early Bronze Age (Minferri, Catalonia), in nieto2018element;textualzoolog.

The zoolog variable referencesDatabase
collects all these
references. It is structured as a named list of named lists, following the
hierarchy described above:
str(referencesDatabase, max.level = 2)

The references' database is organized per taxon. However, in general the
zooarchaeological data to be analysed includes several taxa. Thus, the
reference dataframe should include one reference standard for each relevant
taxon.
The zoolog variable referenceSets
defines four possible
references:
referenceSets
Bos taurus | Bos primigenius | Ovis aries | Ovis orientalis | Capra hircus | Capra aegagrus | Sus domesticus | Sus scrofa | Cervus elaphus | Dama mesopotamica | Gazella gazella | Equus asinus | Equus caballus | Oryctolagus cuniculus | |

Basel | Basel | Basel | Basel | Basel | Basel | |||||||||
Combi | Nieto | Clutton | Clutton | Basel | Basel | Haifa | Haifa | Haifa | Johnstone | Nottingham | ||||
Groningen | Degerbol | Uerpmann | Uerpmann | Hongo |
Each row defines a reference set consisting of a reference source for
each taxon (column). The function
AssembleReference
allows us to build the reference set
taking the selected taxon-specific references from the
referencesDatabase
.
The zoolog variable reference
is a named list including the
references defined by referenceSets

reference$Combi
includes the most comprehensive reference for each
species so that more measurements can be considered. It is the default
reference for computing the log ratios.
If desired, the user can define their own combinations or can also use their own references, which must be a dataframe with the format described above.
referencesDatabase
, refereceSets
, and reference
are exported variables
automatically loaded in memory. In addition, zoolog provides in the
extdata
folder a set of semicolon separated files (csv), generating
them:
referenceSets.csv
Defines referenceSets
.
referencesDatabase.csv
Defines the structure of
referencesDatabase
.
A csv file for each taxon-specific reference, as named in
referencesDatabase.csv
.
