\title{ The example data of the standard deviation for gene expression levels }
\description{
  This data is an artificial example of the standard deviation for gene exapression levels from golden spike-in data set in Choe et al. (2005).

\usage{data(exampleStd)}
\format{
  A 200x6 matrix including 200 genes and 6 chips. The first 3 chips are replicates for 
  C condition and the last 3 chips are replicates for S conditon.
