Evar

the vector of abundances of each species

the number of species in the sample

A utility function to calculate Evar from Smith and Wilson 1996

Univariate and multivariate temporal and spatial diversity indices,
rank abundance curves, and community stability metrics. The functions
implement metrics that are either explicitly temporal and include the
option to  calculate them over multiple replicates, or spatial and include
the option to calculate them over multiple time points. Functions fall into
five categories: static diversity indices, temporal diversity indices,
spatial diversity indices, rank abundance curves, and community stability
metrics. The diversity indices are temporal and spatial analogs to
traditional diversity indices. Specifically, the package includes functions
to calculate community richness, evenness and diversity at a given point in
space and time. In addition, it contains functions to calculate species
turnover, mean rank shifts, and lags in community similarity between two
time points.
