get gene ids by genomic location

retrieve gene ids from txdb object by genomic location.

getGeneIDsFromTxDb(gr, txdb)

Arguments

gr

GRanges object.

txdb

An object of TxDb.

Value

A character vector of gene ids

Examples

library(TxDb.Hsapiens.UCSC.hg19.knownGene)
gr <- parse2GRanges("chr11:122,830,799-123,116,707")
ids <- getGeneIDsFromTxDb(gr, TxDb.Hsapiens.UCSC.hg19.knownGene)
#>   24 genes were dropped because they have exons located on both strands of the
#>   same reference sequence or on more than one reference sequence, so cannot be
#>   represented by a single genomic range.
#>   Use 'single.strand.genes.only=FALSE' to get all the genes in a GRangesList
#>   object, or use suppressMessages() to suppress this message.
