chao1: Chao1 species richness estimator
In statdivlab/CatchMore: Species Richness estimation with CatchAll

Description Usage Arguments Value Note Author(s) Examples

This function implements the Chao1 richness estimate, which is often mistakenly referred to as an index.

1	chao1(input_data, ...)

`input_data`	An input type that can be processed by `convert()` or a `phyloseq` object
`output`	Deprecated; only for backwards compatibility
`answers`	Deprecated; only for backwards compatibility

An object of class alpha_estimate, or alpha_estimates for phyloseq objects

The authors of this package strongly discourage the use of this estimator. It is only valid when you wish to assume that every taxa has equal probability of being observed. You don't really think that's possible, do you?
