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

A UniGene identifier represents a cluster of sequences of a gene. Using
UniGene identifiers one can query the UniGene database for information about
the sequences or the Entrez Gene database for information about the
genes.  

Mappings were based on data provided by:

Entrez Gene:\bsl{}url{ftp://ftp.ncbi.nlm.nih.gov/gene/DATA/}. Built: Source data downloaded from Entrez Gene on Thu Mar 15 17:54:57 2007

Package built Thu Mar 15 18:00:58 2007

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