In SIM: Integrated Analysis on two human genomic datasets

Description

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

Usage

	data(expr.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 expression log-ratios of 41 samples.
