\title{Yeast mRNA Expression Data Cluster Memberships}
\description{ This data set contains cluster membership for yeast genes clustered using mRNA expression from a microarray experiment in Causton, et al. Molecular Biology of the Cell (2001). The 3000 most variable genes were clustered using k-means with 30 clusters.}
\usage{data(mRNAclusters)}
\format{A data frame whose rows are the 3000 genes and whose two columns are gene name and cluster membership number.}
