GenomicAnnotationsFromLibrary: Function extracting a GenomicAnnotations object from a Bioconductor annotation library

Description

Function extracting a GenomicAnnotations object from a Bioconductor annotation library

Usage

GenomicAnnotationsFromLibrary(annotLibrary, probeIDs = NULL,
retain.chrs = NULL, optionalAnnotations = NULL)

Arguments

annotLibrary

Character string containing the name of the annotations library to be used for building the GenomicAnnotations object

probeIDs

Optional: list of reference id from the selected annotLibrary to be used for building the GenomicAnnotations object

retain.chrs

Numeric vector, containing the list of chromosomes selected for the output GenomicAnnotations object. E.g. set retain.chrs=1:22 to limit the GenomicAnnotations object to chromosomes from 1 to 22. This might be ueseful to limit GenomiAnnotations objects to autosomic chromosomes.

optionalAnnotations

Character vector to select additional annotations fields to be included into the GenomicAnnotations object.

Value

An object of class "GenomicAnnotations"
