\keyword{datasets}{rgu34cCHRLOC}
\begin{Description}\relax
rgu34cCHRLOC is an R environment that maps manufacturer ids to the
starting position of the gene. The position of a gene is
measured as the number of base pairs.
\end{Description}
\begin{Details}\relax
Each manufacturer id maps to a named vector of chromosomal locations,
where the name indicates the chromosome. Due to inconsistencies that
may exist at the time the environment was built, these vectors may
contain more than one chromosome and/or location. If the chromosomal
location is unknown, the vector will contain an \code{NA}.

Chromosomal locations on both the sense and antisense strands are
measured as the number of base pairs from the p (5' end of the sense
strand) to q (3' end of the sense strand) arms. Chromosomal locations on the
antisense strand have a leading "-" sign (e. g. -1234567). 

Mappings were based on data provided by:

\begin{Examples}
\begin{ExampleCode}
    # Covert to a list
    xx <- as.list(rgu34cCHRLOC)
    # Remove probe ids that do not map to any CHRLOC
    xx <- xx[!is.na(xx)]
    if(length(xx) > 0){
        # Gets the location for the first five probes
        xx[1:5]
        # Gets the first one
        xx[[1]]
    }
