\title{Map between Manufacturer Identifiers and Gene Symbols}
  @ANNOBJPREFIX@SYMBOL is an R object that provides mappings between
  manufacturer identifiers and gene abbreviations. 
  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: @SYMBOLSOURCE@


    \item \code{\link[AnnotationDbi]{AnnotationDb-class}} for use of
          the \code{select()} interface.

## select() interface:
## Objects in this package can be accessed using the select() interface
## from the AnnotationDbi package. See ?select for details.

## Bimap interface:
# 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
  # Get the first one
