\title{Convert pcaRes object to an expression set}
\usage{asExprSet(object, exprSet)}
\description{This function can be used to conveniently replace the expression
matrix in an \code{ExpressionSet} with the completed data from a
\code{pcaRes} object.}
\details{This is not a standard \code{as} function as \code{pcaRes}
object alone not can be converted to an \code{ExpressionSet} (the
\code{pcaRes} object does not hold any \code{phenoData} for
example).}
\value{An object without missing values of class \code{ExpressionSet}.}
