plot.compositional

an object of class <code>compositional</code>

sname

a boolean flag controlling if the pies of the
pie-chart should be labeled

annotate

an optional string with the name of one of R's
built-in colour palettes (e.g., heat.colors, terrain.colors,
topo.colors, cm.colors), which are to be used for plotting the data.

colmap

optional parameters to be passed on to the graphics object

Plots an object of class <code>compositional</code> as a pie chart

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, multidimensional scaling, generalised procrustes analysis and individual differences scaling using a variety of dissimilarity measures. Univariate provenance proxies, such as single-grain ages or (isotopic) compositions are compared with the Kolmogorov-Smirnov dissimilarity and Sircombe-Hazelton L2-norm. Categorical provenance proxies, such as mineralogical, petrographic or chemical compositions are compared with the Aitchison and Bray-Curtis distances. Also included are tools to plot compositional 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.
