matTraining: Gene expression matrix for training set data

Description

A numerical matrix containing gene expression matrix for 70 genes and 78 breast cancer patients (training set data) from the Glas et al cohort (see the mammaPrintData package).

Usage

data(trainingData)

Format

The matTraining matrix contains normalized expression values for the 70 gene signature (rows) across 78 samples (columns). Group information (emph``bad'' versus ``good'' prognosis) is shown in colnames(matTraining).

Details

This dataset corresponds to the breast cancer patients' cohort published by Glas and colleagues in BMC Genomics (2006). The gene expression matrix was obtained from the mammaPrintData package as described by Marchionni and colleagues in BMC Genomics (2013).
