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.
