\title{ Gene expression stability value M }
\description{
  Computation of the gene expression stability value M for real-time 
  quantitativ RT-PCR data. For more details we refer to 
  Vandesompele et al. (2002). 
}
\usage{
geneStabM(relData, na.rm = FALSE)
}
\arguments{
  \item{relData}{ matrix or data.frame containing real-time quantitative 
  		  RT-PCR data }
  \item{na.rm}{ a logical value indicating whether \code{NA} values should be
          stripped before the computation proceeds. }
}
\details{
  The gene expression stability value M is defined as the average pairwise
  normalization factor; i.e., one needs to specify data from at least two
  genes. For more details see Vandesompele et al. (2002).
}
\value{
  numeric vector with gene expression stability values 
}
