Archaeological Stratigraphy and Chronological Sequences
Overview
A tidy framework for working with archaeological stratigraphy and chronology. Includes tools for reading, analysing, and visualising stratigraphic sequences (Harris matrices) as directed graphs following the definition of Dye and Buck (2015) doi:10.1016/j.jas.2015.08.008 and an R interface to the Chronological Query Language (CQL) used in 'OxCal' by Bronk Ramsey (2009) doi:10.1017/S0033822200033865.
stratigraph()supports tidy/long-format data frames where each row represents a single relation (#15)- Improved validation workflow for stratigraphs
- Validation now considers redundant relations.
strat_is_valid()renamed tostrg_is_valid()(#21) and silently returns a logical value.- Use
strg_validate()to raise an error for invalid stratigraphs orstrg_validate(warn = TRUE)to raise a warning. - Adds
print()method for stratigraphs including validations status - Minimum supported R version is now 4.1
- Removes deprecated
c14_*andcal_*functions. These now live in the c14 package.
