Mappings were based on data provided by: @CHRSOURCE@ } \seealso{ \itemize{ \item \code{\link[AnnotationDbi]{AnnotationDb-class}} for use of the \code{select()} interface. } } \examples{ ## select() interface: ## Objects in this package can be accessed using the select() interface ## from the AnnotationDbi package. See ?select for details. ## Bimap interface: x <- @ANNOBJPREFIX@CHR # 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]] } } \keyword{datasets}
