org.Sc.sgdENTREZID {org.Sc.sgd.db} | R Documentation |
org.Sc.sgdENTREZID is an R object that contains mappings between Systematic ORF accession numbers and NCBI Entrez Gene identifiers.
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
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]] }
