Overview

A convenient and reproducible toolkit for relative and absolute dating and analysis of chronological patterns. This package includes functions for chronological modeling and dating of archaeological assemblages from count data. It provides methods for matrix seriation. It also allows to compute time point estimates and density estimates of the occupation and duration of an archaeological site. kairos provides methods for:

  • Matrix seriation: seriate_rank() and seriate_average()
  • Mean ceramic date estimation (South 1977): mcd()
  • Event and accumulation date estimation (Bellanger and Husi 2012): event()
  • Aoristic analysis (Ratcliffe 2000): aoristic()
  • Chronological apportioning (Roberts et al. 2012): apportion()

tabula is a companion package to kairos that provides functions for visualization and analysis of archaeological count data.

This package is a part of the tesselle project https://www.tesselle.org.

Installation

You can install the released version of kairos from CRAN with:

install.packages("kairos")

And the development version from GitHub with:

# install.packages("remotes")
remotes::install_github("tesselle/kairos")

Usage

## Load packages
library(kairos)
#> Loading required package: dimensio

kairos v2.0 uses aion for internal date representation. Look at vignette("aion") before you start.

It assumes that you keep your data tidy: each variable (type/taxa) must be saved in its own column and each observation (sample/case) must be saved in its own row.

## Data from Husi 2022
data("loire", package = "folio")
keep <- c("Anjou", "Blésois", "Orléanais", "Haut-Poitou", "Touraine")
loire <- subset(loire, area %in% keep)

## Get time range
loire_range <- loire[, c("lower", "upper")]

## Calculate aoristic sum (weights) by group
ao <- aoristic(loire_range, step = 50, weight = TRUE, groups = loire$area)

## Plot
plot(ao, col = "grey")

## Rate of change by group
ro <- roc(ao, n = 30)
plot(ro)
