Mappings were based on data provided by ALL of these sources: \url{ftp://ftp.ensembl.org/pub/current_fasta} \url{ftp://genome-ftp.stanford.edu/pub/yeast/data_download} \url{ftp://ftp.ncbi.nlm.nih.gov/gene/DATA} This mapping is a combination of NCBI to ensembl IDs from BOTH NCBI and ensembl. These mappings are based upon the ensembl table which is contains data from BOTH of these sources in an effort to maximize the chances that you will find a match. Mappings were based on data provided by: Ensembl ftp://ftp.ensembl.org/pub/current\_fasta With a date stamp from the source of: 2010-Aug5 } \examples{ x <- org.Sc.sgdENSEMBL # Get the SGD 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 genes xx[1:5] # Get the first one xx[[1]] } #For the reverse map ENSEMBL2ORF: # Convert to a list xx <- as.list(org.Sc.sgdENSEMBL2ORF) if(length(xx) > 0){ # Gets the SGD gene IDs for the first five Ensembl IDs xx[1:5] # Get the first one xx[[1]] } } \keyword{datasets}
