RichnessIndex

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 and absolute
dating and analysis of (chronological) patterns. It includes functions for
matrix seriation (reciprocal ranking, CA-based seriation), chronological
modeling and dating of archaeological assemblages and/or objects.
Beyond these, the package 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.
