Accessor for genomic feature annotation

Returns the GRanges of genomic features stored in a commaData object. This is the annotation loaded from a GFF3 or BED file at construction time.

Usage

# S4 method for class 'commaData'
annotation(object)

Arguments

object

A commaData object.

Value

A GRanges object. May be empty (length 0) if no annotation was provided when creating the object.

Examples

data(comma_example_data)
annotation(comma_example_data)
