expand.freqs

Expand a matrix or data.frame of species frequencies to full 
 vector.

Functions for calculating species richness for rarefaction and
extrapolation, primarily non-parametric species richness such as
jackknife, Chao1, and ACE. Also available are functions for plotting
species richness and extrapolation curves, and computing standard diversity
and entropy indices.
