pairwiseV {ctrlGene}

Calculates V(n+1/n) values

Description

Useful for establishing the quality of your normalization regime. See Vandesompele 2002 for advice on interpretation.

Usage

pairwiseV(expression, ctVal = TRUE)

Arguments

expression

a matrix of expression levels. Each row corresponds to a sample and each column to a gene.

ctVal

a logical value indicating data type. If ct-values are input, ctVal=TRUE, otherwise, ctVal=FALSE.

Value

A Series of values [V2/3, V3/V4, V4/V5, ...].
