RarefactionIndex-class

.RarefactionIndex

An S4 class to represent an rarefaction measure.

internal

An easy way to examine archaeological count data. This
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.). It allows to easily visualize
count data and statistical thresholds: rank vs abundance plots,
heatmaps, Ford (1962) and Bertin (1977) diagrams, etc.
