\title{Map FlyBase CG Acession numbers with Entrez Gene identifiers}  
\description{ 
  @ANNOBJPREFIX@FLYBASE is an R object that contains mappings between 
  Entrez Gene identifiers and FlyBase CG accession numbers.  These
  accessions are used by ensembl and supported by flybase.    
}

\details{
  This object is a simple mapping of Entrez Gene identifiers
  \url{https://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=gene} to Flybase
  CG accession numbers.

  Mappings were based on data provided by: @FLYBASESOURCE@
}

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

## Bimap interface:
x <- @ANNOBJPREFIX@FLYBASECG
# Get the entrez gene IDs that are mapped to a Flybase CG ID
mapped_genes <- mappedkeys(x)
# Convert to a list
xx <- as.list(x[mapped_genes])
if(length(xx) > 0) {
  # Get the FlyBase CG IDs for the first five genes
  xx[1:5]
  # Get the first one
  xx[[1]]
}
#For the reverse map FLYBASECG2EG:
# Convert to a list
xx <- as.list(@ANNOBJPREFIX@FLYBASECG2EG)
if(length(xx) > 0){
   # Gets the entrez gene IDs for the first five FlyBase CG IDs
   xx[1:5]
   # Get the first one
   xx[[1]]
}
