Description

A list containing an example CGH array data for package cghFLasso

Usage

data(CGH)

Details

In NormalArray and DiseaseArray, each column corresponds to one CGH array, and each row corresponds to one gene/clone. 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 contains CGH measurement of one pseudo chromosome.

Value

CGH is a list of four components:

NormalArray
DiseaseArray
chromosome
nucposition
GBM.y

{a numeric vector of length 990.}
