\title{
quantile discretization normalization
}
\description{
Performs a discretization of continous expression levels to discrete steps.
}
\usage{
normalize.ExpressionSet.qd(ExpressionSet = NULL, nbin = 8, ...)
}

\arguments{
  \item{ExpressionSet}{
An ExpressionSet object.

%%     ~~Describe \code{nbin} here~~
Numeric vector of length 1; indicates the number of binnings for the discretization.
}
  \item{\dots}{
Can be used to pass on parameters to underlying functions.
}
