RedeR.data {RedeR}R Documentation

Pre-processed dataset for RedeR case study.

Description

Preprocessed data from a time-course gene expression and ChIP-on-chip analysis of estrogen receptor (ER) binding sites in MCF7 breast cancer cell line (Carroll et al, 2006).

Usage

data(Carroll2006)

Format

Carroll2006 List containing 'exp', 'tgs', 'ids', and 'bdsites' R objects.

Details

The gene expression dataset consists of 12 time-course Affymetrix U133Plus2.0 microarrays: 3 replicates at 0h, 3 replicates at 3h, 3 replicates at 6h and 3 replicates at 12h. The original dataset is available at GEO database (GSE11324). The gene ER binding site dataset consists of a Bed file of ER ChIP-on-chip experiment. The original dataset is available at http://research.dfci.harvard.edu/brownlab/datasets/index.php (ER sites from the Bed file '1E-5.bed').
