## Yeast Cell Cycle Dataset

### Description

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

### Usage

     data(yeast)

### 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 α 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.
