\title{ Get outliers for the different YAQCStatsObject slots }
\description{
    This function retrives the outliers fot the different quality control metrics
    stored in a YAQCStatsObject. Outliers are defined as being outside of the 
    mean +/- 2 stdev range or mean/2, mean*1.5 for the scale factor.
}
\usage{
  getOutliers(YAQCStatsObject,slot)
}

\arguments{
   \item{YAQCStatsObject}{ an object of type \code{"YAQCStats"} }
   \item{slot}{ an object of type \code{string} describing the slot for which 
                the outliers should be retrieved (see details for possible 
                slot strings)
              }
}

\value{
    An object of type \code{"numeric"} giving the outliers names and values
}

\details{
   The slot strings that can be used are:
    \describe{
     \item{scale factor}{"sfs"}
     \item{average background}{ "avbg"}
     \item{average noise}{"avns"}
     \item{percentage present}{"pp"}
     \item{\eqn{\beta}-actin 3'/5' ratio}{"actin"}
     \item{GAPDH 3'/5' ratio}{"gapdh"}
     \item{internal bioB control}{"biob"}
     \item{internal bioC control}{"bioc"}
     \item{internal bioD control}{"biod"}
     \item{Dap spike control}{"dap"}
     \item{Thr spike control}{"thr"}
     \item{Phe spike control}{"phe"}
     \item{Lys spike control}{"lys"}
     }
}

\examples{
  ## load data
  library(MAQCsubsetAFX)
  data(refA)
  ## create the yaqc object
  qobj <- yaqc(refA[, 3:5])
  ## get outliers for the scale factor
  getOutliers(qobj, "sfs")
}
