iNEXT.4steps (version 1.0.1)
Four-Step Biodiversity Analysis Based on 'iNEXT'
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) for statistical background.
