\begin{Description}\relax
ath1121501SYMBOL is an R object that provides mappings between
manufacturer identifiers and gene abbreviations.
\end{Description}
\begin{Details}\relax
Each manufacturer identifier is mapped to an abbreviation for the
corresponding gene. An \code{NA} is reported if there is no known
abbreviation for a given gene.

Symbols typically consist of 3 letters that define either a single
gene (ABC) or multiple genes (ABC1, ABC2, ABC3). Gene symbols can be
used as key words to query public databases such as Entrez Gene.

Mappings were based on data provided by: Tair ( ftp://ftp.arabidopsis.org/Genes/gene\_aliases.20070806 ) on 2007-Aug2

\begin{Examples}
\begin{ExampleCode}
        x <- ath1121501SYMBOL
        # Get the probe identifiers that are mapped to a gene symbol
        mapped_probes <- mappedkeys(x)
        # Convert to a list
        xx <- as.list(x[mapped_probes])
        if(length(xx) > 0) {
          # Get the SYMBOL for the first five probes
          xx[1:5]
          # Get the first one
          xx[[1]]
        }
