combineTechReps {NormqPCR}R Documentation

Combines Technical Replicates

Description

Takes expression set of qPCR values containing technical replicates and combines them.

Usage

combineTechReps(qPCRBatch, ...)

## S4 method for signature 'qPCRBatch'
combineTechReps(qPCRBatch, calc="arith") 

Arguments

qPCRBatch

Expression set containing qPCR data, read in by a ReadqPCR function and containing technical reps, denoted by _TechRep.n suffix.

...

Extra arguments, detailed below

calc

use median, arithmetic or geometric mean for combining the values

Details

Takes exprs of qPCR values containing technical replicates and combines them using a specified centrality measure.

Value

qPCRBatch with same number of samples, but with less features, since all technical replicates are replaced with a single value of their means.
