\usage{data(hgu95All)}
\description{Data, in the form of environments for the Affymetrix U95A
 chip.}


\format{
  These data sets provide environments with mappings from the Affymetrix
  identifiers to Entrez Gene 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.
