R: Example CGH Array Data

CGH {cghFLasso} | R Documentation

## 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.
