\title{ ExpressionSet object from a RGList}
\description{
	It creates an 'ExpressionSet' object from a 'RGList' containing
	unique ProbeNames  
}
\usage{
build.eset(RGlist, targets, makePLOT, annotation.package)
}
\arguments{
  \item{RGlist}{An RGList containing normally the processed data}
  \item{targets}{data.frame with the targets structure }
  \item{makePLOT}{logical, if \code{TRUE} it makes a 'heatmap' with the 100 greater variance
		genes, a 'hierarchical cluster' with all the genes and a  pca plot}
  \item{annotation.package}{a character specifying the AGI annotation package: 'hgug4112a.db','mgug4122a.db' }
}
\details{
	It creates an ExpressionSet object from a RGList. 
        Usually this function is applied to an RGList object containing
        the processed data. 
}
\value{
	An ExpressionSet object
}
