\title{Selection of features based on their IQR}
   selectFeatures_IQR(data, nb)
   \item{data}{Measured data of dimension features x samples
   (e.g, gene expression data)}
   \item{nb}{The number of features to be selected}
   A subset of \code{data} restricted to the features having
   the \code{nb} highest IQR value
   This function selects the features having the largest
   Inter Quartile Range (IQR).
 dat <- matrix(rnorm(10000),ncol=10,nrow=1000)
 rownames(dat) <- 1:1000
