\HeaderA{YEASTDESCRIPTION}{An annotation data file that maps Open Reading Frame (ORF)
identifiers to textural descriptions of the corresponding genes}{YEASTDESCRIPTION}
\keyword{datasets}{YEASTDESCRIPTION}
\begin{Description}\relax
YEASTDESCRIPTION maps yeast ORF ids to descriptive information
about genes corresponding to the ORF ids
\end{Description}
\begin{Details}\relax
This is an environment object containing key and value pairs. Keys are
ORF ids and values are the corresponding descriptions of genes. Values
are vectors of length 1. Probe ids that can not be mapped to
descriptive information are assigned a value NA.

Annotation based on data provided by:

\begin{ExampleCode}
        require("annotate") || stop("annotate unavailable")
        xx <- as.list(YEASTDESCRIPTION)
        if(length(xx) > 0){
                # Get the value of the first key
                xx[[1]]
                # Get the values for a few keys
                if(length(xx) >= 3){
                        xx[1:3]
                }
