eset2GenomicAnnotations: Function building a GenomicAnnotations object on an ExpressionSet object

Description

Function building a GenomicAnnotations object on an ExpressionSet object

Usage

# eset2GenomicAnnotations(.Object, retain.chrs,
# optionalAnnotations)
eset2GenomicAnnotations(.Object, ...)

Arguments

.Object

ExpressionSet object. The associated annotation library will be used to build a GenomicAnnotations object.

...

See below

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"
