\begin{Description}\relax
This generic function accesses the \code{data.frame} for
the feature-level data, such as annotation of SNPs or genes.  fData is
the analog of \code{pData} that accesses the \code{data.frame} for the
\code{phenoData} \code{\LinkA{AnnotatedDataFrame-class}{AnnotatedDataFrame.Rdash.class}}.
\end{Description}
\begin{Usage}
\begin{verbatim}
fData(object)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{object}] Object, possibly derived from class \code{eSet}
\end{ldescription}
\end{Arguments}
\begin{Details}\relax
\end{Details}
\begin{Value}
\code{fData} and \code{pData} both return data.frames.  \code{fData}
will generally return a very large data.frame as the number of
features is often very large.
\end{Value}
