org.Hs.egENSEMBLTRANS {org.Hs.eg.db} | R Documentation |
org.Hs.egENSEMBL is an R object that contains mappings between Entrez Gene identifiers and Ensembl transcript accession numbers.
This object is a simple mapping of Entrez Gene identifiers https://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=gene to Ensembl transcript accession numbers.
Mappings were based on data provided by: ftp://ftp.ensembl.org/pub/current_fasta ftp://ftp.ncbi.nlm.nih.gov/gene/DATA
AnnotationDb-class
for use of
the select()
interface.
## select() interface: ## Objects in this package can be accessed using the select() interface ## from the AnnotationDbi package. See ?select for details. ## Bimap interface: x <- org.Hs.egENSEMBLTRANS # Get the entrez gene IDs that are mapped to an Ensembl ID mapped_genes <- mappedkeys(x) # Convert to a list xx <- as.list(x[mapped_genes]) if(length(xx) > 0) { # Get the Ensembl gene IDs for the first five proteins xx[1:5] # Get the first one xx[[1]] } #For the reverse map ENSEMBLTRANS2EG: # Convert to a list xx <- as.list(org.Hs.egENSEMBLTRANS2EG) if(length(xx) > 0){ # Gets the entrez gene IDs for the first five Ensembl IDs xx[1:5] # Get the first one xx[[1]] }
