acgh.data: Array Comparative Genomic Hybridization data

In SIM: Integrated Analysis on two human genomic datasets

Description

Copy number data taken from Pollack et al. PNAS. 2002, 99(20): 12963-8.

Usage

	data(acgh.data)

Format

A data frame with 99 observations on 45 variables. The first 4 columns are the unique identifier, symbol for the chromosome and start position of the probe the next 41 columns are the copy number measurements of 41 samples.

Details

A subset of the original data is taken namely all the probes on the long arm of chromosome 8.
