qunormaddon {bapred}

Addon quantile normalization using “documentation by value” (Kostka & Spang, 2008)

Description

Performs addon quantile normalization by using documentation by value (Kostka & Spang, 2008).

Usage

qunormaddon(params, x)

Arguments

params

object of class qunormtrain. Contains parameters necessary for addon quantile normalization.

x

matrix. The covariate matrix of the new data. Observations in rows, variables in columns.

Details

This function uses code from the off-CRAN package docval, version 1.0.
