stratigraphr: Archaeological Stratigraphy and Chronological Sequences

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>.
