STATegRa (version 1.0.0)

createOmicsExpressionSet: Create an ExpressionSet object since omics dataset.

Description

This function allow to the user to create a ExpressionSet object from a matrix representing an omics dataset. It allows to include the experimental design and annotation in the ExpressionSet object.

Usage

createOmicsExpressionSet(Data,pData=NULL,pDataDescr=NULL,feaData=NULL,feaDataDescr=NULL)

Arguments

Data

Matrix with omics dataset.

pData

Matrix indicating the phenotype of the samples (columns). rownames(pData)==colnames(exprs)

pDataDescr

Description of the phenotypic data

feaData

Matrix indicating the variables/features annotation

feaDataDescr

Description of the feature annotation

Value

A object of class ExpressionSet

Details

In Data matrix, samples has to be in columns and variables has to be in rows

Examples

data(STATegRa_S3)
B1 <- createOmicsExpressionSet(Data=Block1.PCA,pData=ed.PCA,
                               pDataDescr=c("classname"))
B2 <- createOmicsExpressionSet(Data=Block2.PCA,pData=ed.PCA,
                               pDataDescr=c("classname"))
