\arguments{
 \item{object}{An object of class \code{\link[affy:AffyBatch-class]{AffyBatch}}.}
  }
\details{
  This creates the sixth page of a \code{\link[affyQCReport:QCReport]{QCReport}} report. 
  The page displays array-array intensity correlation coefficients for all pairs of arrays in an \code{\link[affy:AffyBatch-class]{AffyBatch}} object. Arrays are ordered according to phenotypic data if available. This plot is useful for detecting outlier arrays.
  
More details are available in the vignette.
