yeast: Yeast Cell Cycle Dataset

Description

This is the Yeast Cell Cycle dataset used in Chun and Keles (2010).

Usage

data(yeast)

Arguments

Format

A list with two components:

x

ChIP-chip data. A matrix with 542 rows and 106 columns.

y

Cell cycle gene expression data. A matrix with 542 rows and 18 columns.

Details

Matrix y is cell cycle gene expression data (Spellman et al., 1998) of 542 genes from an \(\alpha\) factor based experiment. Each column corresponds to mRNA levels measured at every 7 minutes during 119 minutes (a total of 18 measurements). Matrix x is the chromatin immunoprecipitation on chip (ChIP-chip) data of Lee et al. (2002) and it contains the binding information for 106 transcription factors. See Chun and Keles (2010) for more details.
