SPECIES: An r package for species richness estimation

We introduce an r package species for species richness or diversity estimation. this package provides simple r functions to compute point and condence interval estimates of species number from a few nonparametric and semi-parametric methods. for the methods based on nonparametric maximum likelihood estimation,the r functions are wrappers for fortran codes for better eciency. all functions in this package are illustrated using real data sets.
