%description
Expands 'iNEXT' to include the estimation of sample completeness and
evenness. The package provides simple functions to perform the following
four-step biodiversity analysis: STEP 1: Assessment of sample completeness
profiles. STEP 2a: Analysis of size-based rarefaction and extrapolation
sampling curves to determine whether the asymptotic diversity can be
accurately estimated. STEP 2b: Comparison of the observed and the
estimated asymptotic diversity profiles. STEP 3: Analysis of
non-asymptotic coverage-based rarefaction and extrapolation sampling
curves. STEP 4: Assessment of evenness profiles. The analyses in STEPs 2a,
2b and STEP 3 are mainly based on the previous 'iNEXT' package. Refer to
the 'iNEXT' package for details. This package is mainly focusing on the
computation for STEPs 1 and 4. See Chao et al. (2020)
<doi:10.1111/1440-1703.12102> for statistical background.
