singh2002: Prostate Cancer Study of Singh et al. (2002)

Description

Gene expression data (6033 genes for 102 samples) from the microarray study of Singh et al. (2002).

Usage

data(singh2002)

Format

singh2002$x is a 102 x 6033 matrix containing the expression levels. The rows contain the samples and the columns the genes.

singh2002$y is a factor containing the diagnosis for each sample ("cancer" or "healthy").

Details

This data set contains measurements of the gene expression of 6033 genes for 102 observations: 52 prostate cancer patients and 50 healty men.
