org.Hs.egCHR {org.Hs.eg.db} | R Documentation |
org.Hs.egCHR is an R object that provides mappings between entrez gene identifiers and the chromosome that contains the gene of interest.
Each entrez gene identifier maps to a vector of a chromosome.
Mappings were based on data provided by: Entrez Gene ( ftp://ftp.ncbi.nlm.nih.gov/gene/DATA ) on 2008-Apr2
x <- org.Hs.egCHR # Get the entrez gene 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]] }
