\begin{Description}\relax
ygs98ORF is an R object that provides mappings between
manufacturer and ORF identifiers.
\end{Description}
\begin{Details}\relax
Each manufacturer identifier is mapped to a vector of ORF identifiers. The length of
the vector may be one or longer, depending on how many ORF identifiers the
manufacturer identifier can be mapped to. An \code{NA} is reported for any
manufacturer identifier that cannot be mapped to an ORF identifier at this time.

\begin{Examples}
\begin{ExampleCode}
        x <- ygs98ORF
        # Get the probe identifiers that are mapped to ORF identifiers
        mapped_probes <- mappedkeys(x)
        # Convert to a list
        xx <- as.list(x[mapped_probes])
        if(length(xx) > 0) {
          # Get the ORF identifiers for the first five probes
          xx[1:5]
          # For the first probe
          xx[[1]]
        }
