Overview

About

Maintained by Sebastien PlutniakCRAN page ↗GitHub ↗Issues ↗

Methods to analyse spatial units in archaeology from the refitting relationships between fragments of objects scattered in these units (e.g. stratigraphic layers). Graphs are used to model archaeological observations. The package is mainly based on the 'igraph' package for graph analysis. Functions can: 1) create, manipulate, visualise, and simulate fragmentation graphs, 2) measure the cohesion and admixture of archaeological spatial units, and 3) characterise the topology of a specific set of refitting relationships. A series of published empirical datasets is included. Documentation about 'archeofrag' is provided by a vignette and by the accompanying scientific papers: Plutniak (2021, Journal of Archaeological Science, doi:10.1016/j.jas.2021.105501) and Plutniak (2022, Journal of Open Source Software, doi:10.21105/joss.04335). This package is complemented by the 'archeofrag.gui' R package, a companion GUI application available at https://analytics.huma-num.fr/archeofrag/.

Changes in 1.3.0

Released: 2026-XX-XX

New method to compute a cohesion value for a graph with one spatial unit, implemented in frag.layers.cohesion(). It uses a new internal .frag.graph.mirror() function.
Graph having only one or no spatial unit (i.e. 'layer.attr' vertex attribute) are now supported.
Node size in frag.graph.plot() can now be controlled with the 'node.size' parameter.
Addition of new datasets: 'Barger Gulch', 'Bessinaudes', 'Champ Parel 3', 'Chez Thuilet', 'Peyrazet', and 'Rue Auguste Isaac 35'.
Datasets include additional metadata: 'observed.spatial.units' (number of documented archaeologically relevant observed spatial units), 'doi' (digital object identifier of the published dataset).
Correct the error in frag.graph.plot() when coordinates variable were 'x', 'y', 'z'.

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("archeofrag", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("sebastien-plutniak/archeofrag")

Development version from sebastien-plutniak/archeofrag. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-archeofrag

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-archeofrag

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-archeofrag

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
