Map ORF IDs to Chromosomes

Description

org.Sc.sgdCHR is an R object that provides mappings between ORF identifiers and the chromosome that contains the gene of interest.

Details

Each ORF identifier maps to a vector of a chromosome.

Mappings were based on data provided by: Yeast Genome http://downloads.yeastgenome.org/ With a date stamp from the source of: 07-Sep-2013

Examples

        x <- org.Sc.sgdCHR
        # Get the ORF identifiers that are mapped to a chromosome
        mapped_genes <- mappedkeys(x)
        # Convert to a list
        xx <- as.list(x[mapped_genes])
        if(length(xx) > 0) {
          # Get the CHR for the first five genes
          xx[1:5]
          # Get the first one
          xx[[1]]
        }
