org.Dr.egZFIN {org.Dr.eg.db} | R Documentation |
org.Dr.egZFIN is an R object that contains mappings between Entrez Gene identifiers and Zfin accession numbers.
This object is a simple mapping of Entrez Gene identifiers http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=gene to Zfin Accession Numbers.
Mappings were based on data provided by: Entrez Gene ( ftp://ftp.ncbi.nlm.nih.gov/gene/DATA ) on 2008-Sep2
x <- org.Dr.egZFIN # Get the entrez gene IDs that are mapped to a Zfin ID mapped_genes <- mappedkeys(x) # Convert to a list xx <- as.list(x[mapped_genes]) if(length(xx) > 0) { # Get the Zfin gene IDs for the first five genes xx[1:5] # Get the first one xx[[1]] }
