NormalyzerStatistics {NormalyzerDE}R Documentation

Class representing a dataset for statistical processing in NormalyzerDE

Description

Is initialized with an annotation matrix, a data matrix and a design data frame. This object can subsequently be processed to generate statistical values and in turn used to write a full matrix with additional statistical information as well as a graphical report of the comparisons.

Usage

NormalyzerStatistics(experimentObj, logTrans = FALSE)

NormalyzerStatistics(experimentObj, logTrans = FALSE)

Arguments

experimentObj

Instance of SummarizedExperiment containing matrix and design information as column data

logTrans

Whether the input data should be log transformed

Value

nds Generated NormalyzerStatistics instance
