stratigraphr is a tidy framework for working with archaeological stratigraphy and chronology in R. It includes tools for reading, analysing, and visualising stratigraphies (Harris matrices) and sequences as directed graphs; helper functions for using radiocarbon dates in a tidy data analysis; and an R interface to OxCal’s Chronological Query Language (CQL).


You can install the development version of stratigraphr from GitHub:

# install.packages("devtools")

Please note that this package is in an early stage of development. It is functional, but many features are missing and future versions are likely to contain breaking changes.
