\begin{Description}\relax
gahgu95bCHR is an R environment that provides mappings between a
custom probeset identifier and the chromosome that contains the gene of interest.
\end{Description}
\begin{Details}\relax
Each identifier maps to a chromosome.
If the chromosomal location is unknown,
the vector will contain an \code{NA}.

Mappings were based on data provided by:

\begin{ExampleCode}
        # Convert to a list
        xx <- as.list(gahgu95bCHR)
        # Remove probe identifiers that do not map to any chromosome
        xx <- xx[!is.na(xx)]
        if(length(xx) > 0){
            # Get the chromosome number for the first five probes
            xx[1:5]
            # Get the first one
            xx[[1]]
        }
