Estimate probabilities of find numbers per period.

archeofrag

R package for the analysis of the fragmentation of archeological objects.

Artifacts-Analyzer

Python script for analyzing data sets of archaeological artifacts containing only Boolean and categorical variables.

BasicMapping

Working with map data in R.

Binomial-Co-occurrence-Assessment

R script that implements a means for statistically assessing the degree of co-occurrence between classes within a dataset.

Bootstrap-Correspondence-Analysis

R-script for conducting and evaluating bootstrapped correspondence analyses.

Brainerd-Robinson-Similarity-Coefficient-and-Sampling-Error-Assessment

Script for calculating Brainerd-Robinson coefficients based on tabular count or percent data. This script also estimates the probability that a given difference between two samples is the product of sampling error.

ca

R Script for Seriation Using Correspondence Analysis.

CAinterprTools

R package to help interpreting Correspondence Analysis’ results.

CAseriation

R Package for contingency tables seriation via Correspondence Analysis.

chi-field-manual

A bookdown powered manual for the small scale cultural heritage organization looking to leverage various chi techniques for their own collections.

chronup

Tools for chronological uncertainty propagation.

cTransmission

An Approximate Bayesian Computation Framework for inferring patterns of cultural transmission from frequency data.

DIGSS

A simulation tool to estimate the rate of success that surveys possessing user-specific characteristics have in identifying archaeological sites (or any groups of clouds of objects), given specific parameters of survey area, survey methods, and site properties.

dimensio

Simple Principal Components Analysis (PCA) and Correspondence Analysis (CA) based on the Singular Value Decomposition (SVD). This package provides S4 classes and methods to compute, extract, summarize and visualize results of multivariate data analysis. It also includes methods for partial bootstrap validation.

Explographe

Application (in LibreOffice Calc) for serializing a graphic matrix from counting tables. The application makes it possible to obtain either a serograph or a graph of the PVI matrograph type (visualization of the differences in independence from the percentages of independence values) which does not favor the vision of the variables over that of the lines and more suitable for non-chronological treatments.

Geostat

Code for Geostatistics in ethnographic contexts.

Kmeans

Script for conducting K-means cluster analysis using R. This script provides output designed to help the user select an appropriate cluster solution.

kriging

Codes for performing kriging for ethnographic and archaeological data.

lecAAR

Tool for calculating the largest empty circles and estimation of archaeological sites theoretically to be expected in region of interest, an implementation of the method published by Andreas Zimmermann and Karl Peter Wendt (2003).

LISA

Moran’s I and Getis-Ord G* Analysis.

Mean-Ceramic-Date-and-Error-Estimation

Script for calculating mean ceramic dates based on tabular data. This script also estimates sampling error using a bootstrapping procedure.

Near-Presence-Analysis

R script for analyzing presence/absence data in irregularly distributed archaeological survey units.

nearpresence

Implements Near Presence Cluster Analysis, a statistical method for identifying spatial clustering within presence / absence data observed in irregularly distributed areal observation units.

p2pPerm

A function for retrieving metrics for resistance-resilience from rcarbon permTest objects.

paleocar

An R package implementing functions to perform spatio-temporal paleoclimate reconstruction from tree-rings using the CAR (Correlation Adjusted corRelation) approach of Zuber and Strimmer.

PLC

Pure Locational Clustering.

PointPattern

Point Pattern Analysis.

predictSource

A package to analyze data used to determine whether samples from multiple sources can be separated, to predict the sources of samples from unknown sources, and to evaluation the validity of those predictions. Sample data can include both quantitative and qualitative data. The package includes functions for creating an analysis file from multiple files and exploratory data analysis, as well as multivariate statistical methods to determine source separation, predict sources of unknown samples, and evaluate the validity of the predictions (principal components, classification trees, and random forests).

quantAAR

R Library for Quantitative Analysis in Archaeology.

quantatools

Finding quantum in archaeological data using cosine quantogram and related statistical methods.

rdss

An R package to facilitate the use of Murail et al.’s (1999) approach of sex estimation in past populations.

roev

Functions for analysing and visualizing rates of evolution.

seriation

R package that provides the infrastructure for ordering objects with an implementation of several seriation/sequencing/ordination techniques to reorder matrices, dissimilarity matrices, and dendrograms (see below for a full list). Also provides (optimally) reordered heatmaps, color images and clustering visualizations like dissimilarity plots, and visual assessment of cluster tendency plots (VAT and iVAT).

Seriation

Algorithms, implementations, manuscripts, and test cases for iterative deterministic frequency seriation done by agglomeration.

sindwem

This R package contains exactly one function, that calculates the “sum of individual weighted means” according to a methodology that is quite common among archaeologists and was first published in 1988 by Elisabeth Fentress and Philip Perkins.
