\title{Coerce 'rpa' object into an 'ExpressionSet'}

\description{An instance of 'rpa' class contains differential gene
expression estimates in the variable 'd'. The function 'rpa2eset'
coerces this into an ExpressionSet object to allow downstream analysis
of the results using standard R/BioC tools for gene expression data.}

\usage{rpa2eset(x)}

\arguments{
  \item{x}{An instance of the rpa class.}
}

\value{An 'ExpressionSet' object.}
