\title{This function plots the sample relations based on multidimensional scaling using the plotMDS.dge edgeR function}
\description{ This function is a variation on the usual multdimensional scaling
     (or principle coordinate) plot, in that a distance measure
     particularly appropriate for the digital gene expression (DGE)
     context is used. The distance between each pair of samples
     (columns) is the square root of the common dispersion for the top
     genes which best distinguish that pair of samples. These
     top genes are selected according to the tagwise
     dispersion of all the samples.}
