In prostarproteomics/DAPAR: Tools for the Differential Analysis of Proteins Abundance with R

Normalisation QuantileCentering

Description

Normalisation QuantileCentering

Usage

QuantileCentering(
  qData,
  conds = NULL,
  type = "overall",
  subset.norm = NULL,
  quantile = 0.15
)

Arguments

qData	xxx
conds	xxx
type	"overall" (shift all the sample distributions at once) or "within conditions" (shift the sample distributions within each condition at a time).
subset.norm	A vector of index indicating rows to be used for normalization
quantile	A float that corresponds to the quantile used to align the data.

Value

A normalized numeric matrix
