\begin{Description}\relax
drosophila2UNIGENE is an R environment that provides mappings between
manufacturer ids and UniGene ids.
\end{Description}
\begin{Details}\relax
Each manufacturer id is mapped to a UniGene id. An \code{NA} is
reported if the manufacturer id cannot be mapped to UniGene at this time. 

A UniGene id represents a cluster of sequences of a gene. Using
UniGene ids one can query the UniGene database for information about
the sequences or the LocusLink database for information about the
genes.  

Mappings were based on data provided by:

Entrez Gene:\url{http://gopher5/compbio/annotationSourceData/ftp.ncbi.nlm.nih.gov/gene/DATA/}. Built: Source data downloaded from Entrez Gene on Tue May 17 18:36:42 2005

\begin{Examples}
\begin{ExampleCode}
    # Convert the environment to a list
    xx <- as.list(drosophila2UNIGENE)
    # Remove probe ids that do no map to any UniGene id
    xx <- xx[!is.null(xx)]
    if(length(xx) > 0){
        # The UniGene ids for the first two elements of XX
        xx[1:2]
        # Get the first one
        xx[[1]]
    }
