Dataset of class eSet with the raw 'CEL file' intensities

Description

The data are from an experiment that used Affymetrix Scerevisiaetiling chips from 2004, which where custom-made for the Stanford Genome Center. The chips tile the complete genome of S. cerevisiae in steps of 8 bases, separately for each strand of each chromosome. The two tiles for one chromosome (Watson and Crick strands) are offset by 4 bases.

Note that the class eSet was used instead of AffyBatch since the additional overhead of 'CDF environments' in the latter is not needed here.

Usage

data("davidTiling")

Format

Intensity data for 8 arrays. The phenoData slot contains the file names and the nucleic acid type.
