Extracting information in genomic regions of interest

Very often, you'll want to look in more detail at data that falls in a particular genomic region of interest, whether that be the SNPs and variants in a gene or the genes in a particular locus. This extremely common task is handled very well by the extremely powerful GRanges and SummarizedExperiment objects, which are a little fiddly to set up but have very flexible subsetting operations that make the effort well worth it. We'll look at a few ways to set up these objects and a few ways we can manipulate them to get interesting information.

Getting ready

In this recipe, we need the GenomicRanges, SummarizedExperiment, and rtracklayer Bioconductor packages. We&apos...
