Map Systematic ORF identifiers with Entrez Gene identifiers

Description

org.Sc.sgdENTREZID is an R object that contains mappings between Systematic ORF accession numbers and NCBI Entrez Gene identifiers.

Details

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

Mappings were based on data provided by: Entrez Gene ftp://ftp.ncbi.nlm.nih.gov/gene/DATA With a date stamp from the source of: 2011-Sep14

Examples

    x <- org.Sc.sgdENTREZID
    # Get the ORF IDs that are mapped to an Entrez Gene ID
    mapped_genes <- mappedkeys(x)
    # Convert to a list
    xx <- as.list(x[mapped_genes])
    if(length(xx) > 0) {
      # Get the Entrez gene IDs for the first five genes
      xx[1:5]
      # Get the first one
      xx[[1]]
    }
