CGHDisease1: An example of CGH array.

In ISBF: Iterative Selection of Blocks of Features - ISBF

Description

An example of CGH array for the package ISBF. Taken from the package cghFLasso.

Usage

data(CGHDisease1)

Format

A list of 3 (data, chr, nucposi).

Details

The package cghFLasso contains several CGH arrays, in two categories (normal, and disease). This is just a copy of the first array in the disease category. Quoting the package cghFLasso: 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. chr and nucposi provide chromosome number and nucleotide position for each gene/clone.
