\begin{Description}\relax
org.Sc.sgdGENENAME is an R object that maps ORF
identifiers to the corresponding gene name.
\end{Description}
\begin{Details}\relax
Each ORF identifier maps to a named vector containing the gene
name. The vector name corresponds to the ORF 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: Yeast Genome ( ftp://genome-ftp.stanford.edu/pub/yeast/data\_download ) on 2008-Mar29

\begin{Examples}
\begin{ExampleCode}
        x <- org.Sc.sgdGENENAME
        # Get the gene names that are mapped to an ORF identifier
        mapped_genes <- mappedkeys(x)
        # Convert to a list
        xx <- as.list(x[mapped_genes])
        if(length(xx) > 0) {
          # Get the GENE NAME for the first five genes
          xx[1:5]
          # Get the first one
          xx[[1]]
        }
