rnb.get.mapping {RnBeads} | R Documentation

## rnb.get.mapping

### Description

Gets the mapping information used for a region type. These are structures used to map regions to the genomic loci (or Infinium probes) that target them.

### Usage

    rnb.get.mapping(region.type, target.type, assembly = "hg19")

### Arguments

`region.type` | Region type. The built-in types are `"cpgislands"`, `"genes"`, `"promoters"` and `"tiling"`.
`target.type` | Target type for sites.
`assembly` | Genome assembly of interest. See `rnb.get.assemblies` for the list of supported genomes.

### Value

`list` of mapping structures, one per chromosome. Every mapping structure is an object of type `IRanges` and stores the range of indices of all sites contained in the respective region. Regions that do not contain sites are left out of the mapping.

### Examples

    promoters2probes <- rnb.get.mapping("promoters", "probes450")
    promoters2probes[["chr21"]]
