Bundles a number of established statistical methods to facilitate the visual interpretation of large datasets in sedimentary geology. Includes functionality for adaptive kernel density estimation, principal component analysis, correspondence analysis, multidimensional scaling, generalised procrustes analysis and individual differences scaling using a variety of dissimilarity measures. Univariate provenance proxies, such as singlegrain ages or (isotopic) compositions are compared with the KolmogorovSmirnov, Kuiper or SircombeHazelton L2 distances. Categorical provenance proxies such as chemical compositions are compared with the Aitchison and BrayCurtis distances, and pointcounting data with the chisquare distance. Also included are tools to plot compositional and pointcounting data on ternary diagrams, to calculate the sample size required for specified levels of statistical precision, and to assess the effects of hydraulic sorting on detrital compositions. Includes an intuitive querybased user interface for users who are not proficient in R.
