\title{
Yeast cell cycle time series data
}
\description{
Preprocessed time series measurements of four genes from the yeast cell cycle data by Spellman et al.
}
\usage{data(yeastTimeSeries)}
\format{
  A matrix with 14 measurements for the genes Fhk2, Swi5, Sic1, and Clb1. Each gene is a row of the matrix, and each column is a measurement.
}
\details{
The data were obtained from the web site of the yeast cell cycle analysis project at \url{http://genome-www.stanford.edu/cellcycle}. The time series synchronized with the elutriation method were extracted for the genes Fhk2, Swi5, SIC1, and Clb1. In a preprocessing step, missing values were imputed by taking the means of the measurements of the same genes at neighbouring time points.
