CGH: Example CGH Array Data

Description

A list of four components (an example CGH array data for package cghFLasso)

Usage

data(CGH)

Format

Both NormalArray and DiseaseArray are muneric matrix of 2270 rows and 3 columns: each row corresponds to one gene/clone, and each column corresponds to one CGH array. The value of each entry is the log fluorescence ratio resulted from the CGH experiment. The order of the genes/clones in the rows is the same as the order of the genes/clones on the genome. chromosome and nucposition provide chromosome number and nucleotide position for each gene/clone. \ GBM.y is a numeric vertor of length 990, providing CGH measurement of one pseudo chromosome.
