\begin{Description}\relax
Data, in the form of environments for the Affymetrix U95A
chip.
\end{Description}
\begin{Usage}
\begin{verbatim}data(hgu95All)\end{verbatim}
\end{Usage}
\begin{Format}\relax
These data sets provide environments with mappings from the Affymetrix
identifiers to LocusLink identifiers.
The environment functions like a hashtable and can be accessed using
\code{mget}.
If the returned value is \code{NA} then the current 
mapping was unable to identify this. Mappings and data sources are
constantly evolving so updating often is recommended.
\end{Format}
\begin{Source}\relax
The \code{AnnBuilder} package.

\begin{Examples}
\begin{ExampleCode}
 data(hgu95All)
 data(eset)
 mget(geneNames(eset)[330:340], env=hgu95All, ifnotfound=NA)

\end{ExampleCode}
