ReplaceOutliersByMAD(object, replaceOutlier = TRUE, cutoff = 2,
  baseMean = 100, limitMad = 0.707, spriors = 2, Caseon = TRUE, ...)

Arguments

object

a ABSSeq object with element of 'counts' and 'normMethod', see the constructor functions ABSDataSet.

replaceOutlier

switch for replacing, default is TRUE.

cutoff

cutoff of moderating MAD for outliers, default is 2

baseMean

parameter for limiting the trimming at low expression level by baseMean/(sample size), default is 100.

limitMad

the minimal prior for moderating MAD, default is set to 0.707, which is usually the highest standard deviation at expression level of 1

spriors

prior weight size for prior MAD, default is 2

Caseon

switch for dealing with outlier trimming at sample size of 2

...

reserved parameters

Details

Given a matrix of count data, this function replacing the outliers by MAD. Noticely, this function also provides part of parameters for DEs calling. It is called by callParameter

Value

a ABSDataSet object with normalized counts after trimming (replaceOutlier=TRUE) or not (replaceOutlier=FALSE). Use the excounts to show it. Use results with name 'trimmed' to view the trimming status.
