GenomicAnnotationsFromLibrary {PREDA} | R Documentation |
Function extracting a GenomicAnnotations object from a Bioconductor annotation library
GenomicAnnotationsFromLibrary(annotLibrary, probeIDs = NULL, retain.chrs = NULL, optionalAnnotations = NULL)
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. |
An object of class "GenomicAnnotations"
