\begin{Description}\relax
drosophila2GENENAME is an R environment that maps manufacturer
identifiers to the corresponding gene name.
\end{Description}
\begin{Details}\relax
Each manufacturer identifier maps to a named vector containing the gene
name. The vector name corresponds to the manufacturer identifier. If the gene
name is unknown, the vector will contain an \code{NA}.

Gene names currently include both the official (validated by a
nomenclature committee) and preferred names (interim selected for
display) for genes. Efforts are being made to differentiate the two
by adding a name to the vector.

Mappings were based on data provided by:

\begin{Examples}
\begin{ExampleCode}
     # Convert to a list
     xx <- as.list(drosophila2GENENAME)
     # Remove probes that do not map to any GENENAME
     xx <- xx[!is.na(xx)]
     if(length(xx) > 0){
         # Gets the gene names for the first five probe identifiers
         xx[1:5]
         # Get the first one
         xx[[1]]
     }
