ExpressionSetList-class {XDE}

R Documentation

A class for containing a list of ExpressionSets

Description

Each element in the list must be a valid ExpressionSet. The featureNames must be identical for each ExpressionSet.

Objects from the Class

Objects can be created by calls of the form new("ExpressionSetList", ...).

Slots

.Data:

Object of class "list"

Extends

Class "list", from data part. Class "vector", by class "list", distance 2. Class class.AssayData, by class "list", distance 2.

Methods

"["

signature(x = "ExpressionSetList") Subsets each ExpressionSet element in the list.

coerce

signature(from = "list", to = "ExpressionSetList") Coerces a list of ExpressionSet objects to an object of class ExpressionSetList. The validityMethod for the ExpressionSetList class will return an error if the featureNames for each ExpressionSet are not identical.

dim

signature(x="ExpressionSetList") applies dim to each element of the list.

featureNames

signature(object = "ExpressionSetList") Accessor for the featureNames

geneCenter

signature(object = "ExpressionSetList") See geneCenter

lapply

signature(object="ExpresssionSetList") Coerces instance of ExpressionSetList to a list and does lapply on the list. Returns an object of class ExpressionSetList

nSamples

signature(x = "ExpressionSetList") Numerical vector giving the number of samples in each ExpressionSet

nrow

signature(x = "ExpressionSetList") Numerical: number of features or genes

pData

signature(object = "ExpressionSetList") returns a list of data.frames. The elements of the list correspond to the studies in the ExpressionSetList object.

phenotype

signature(object="ExpressionSetList", varLabel="character") Accessor for the clinical variable. Assumes that the clinical variable has the same name in each study.

standardizeSamples

signature(object = "ExpressionSetList") See standardizeSamples

studyCenter

signature(object = "ExpressionSetList") See studyCenter

zeroNu

signature(object = "ExpressionSetList") See zeroNu.
