A thesaurus of canonical (matching those given in c14_labs) radiocarbon laboratory codes and variants of these codes observed in various published datasets.
Format
A data frame with 688 rows and 2 variables:
- canon
Character. The preferred code for the laboratory.
- variant
Character. Variant codes.
Details
The thesaurus aims to be precise and conservative. That is, canonical forms are only given for variants when they can be unambiguously interpreted as that of a known laboratory listed in c14_labs. It is case sensitive, because there are laboratory codes that can only be distinguished by case (see c14_labs for examples).
Variants that cannot (or have not yet) been unambiguously matched to a
known, standard lab code have a canon value of NA.
