rarefy_coverage: Calculate rarefied diversity estimates along coverage (e.g....

In T-Engel/hammeRs:

Description

This function is similar to iNEXT's estimateD(). It allows interpolation and extrapolation of diversities (of order q) along coverage. It is much faster than estimateD() for individual point estimates and uses data inputs like vegan and mobr (i.e site by species matrix). It uses iNext's internal function invChat.Ind() to do the interpolation/ extrapolation. If no C is NULL, it will default to maximum recommendable sample coverage (using recommended_C()).

Usage

rarefy_coverage(m, C = NULL, q = 0)

Arguments

m	site by species matrix or single vector
C	Numeric value between 0 and 1 specifying desired coverage level.
q	integer vector of diversity orders

Value

a vector if q is a single value; a matrix if q is a vector.
