.CompositionIndex

An S4 class to represent a diversity measure.

An easy way to examine archaeological count data. This
package provides a convenient and reproducible toolkit for relative
dating by matrix seriation (reciprocal ranking, CA-based seriation).
It also provides several tests and measures of diversity:
heterogeneity and evenness (Brillouin, Shannon, Simpson, etc.),
richness and rarefaction (Chao1, Chao2, ACE, ICE, etc.), turnover and
similarity (Brainerd-Robinson, etc.). The package make it easy to
visualize count data and statistical thresholds: rank vs abundance
plots, heatmaps, Ford (1962) and Bertin (1977) diagrams.
