R: Get Reference to Approximate CLR

getReference {propr} | R Documentation

## Get Reference to Approximate CLR

### Description

This function finds the reference that is most proportional to the geometric mean of the samples. Using this reference for an alr-transformation will permit an analysis that resembles that of a clr-transformation, but arguably with greater interpretability.

### Usage

    getReference(counts, alpha = NA)

### Arguments

`counts` | A data.frame or matrix. A "count matrix" with subjects as rows and features as columns. Note that this matrix does not necessarily have to contain counts.
`alpha` | A double. See vignette for details. Leave missing to skip Box-Cox transformation.

### Value

A reference as a character or integer.
