Description Usage Arguments Details Value Author(s) References Examples

This function calculates the unique number of features seen in each sample.

1	richness_calc(omicsData, index = c("observed", "chao1", "ace", "break"))

`omicsData`	an object of the class 'seqData' created by `as.seqData`.
`index`	a character vector stating which of the calculations to perform - "observed" for the observed richness, "chao1" the bias-corrected chao1 richness estimator, and/or "ace" for the abundance-based coverage richness estimator. Default is to perform all 3 calculations.

Calculates richness of count data

An object of class richRes (also a data.frame) containing the richness value for every sample in the data object.
