Map Entrez Gene identifiers with FlyBase Acession numbers

Description

indacFLYBASE is an R object that contains mappings between Entrez Gene identifiers and FlyBase accession numbers.

Details

This object is a simple mapping of Entrez Gene identifiers http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=gene to Flybase Accession Numbers.

Mappings were based on data provided by: Entrez Gene ( ftp://ftp.ncbi.nlm.nih.gov/gene/DATA ) on 2007-Aug23

Examples

    x <- indacFLYBASE
    # Get the entrez gene identifiers that are mapped to a FLYBASE ID
    mapped_genes <- mappedkeys(x)
    # Convert to a list
    xx <- as.list(x[mapped_genes])
    if(length(xx) > 0) {
      # Get the FlyBase IDs for the first five genes
      xx[1:5]
      # Get the first one
      xx[[1]]
    }
    # For the reverse map:
    # Convert to a list
    xx <- as.list(indacFLYBASE2PROBE)
   if(length(xx) > 0){
       # Get the probe identifiers for the first five IDs
       xx[1:5]
       # Get the first one
       xx[[1]]
    }
