Extracts the requested annotation for the given genome.
Name of annotation.
Genome assembly of interest. See
When the returned value is of type
GRangesList, it defines the genomic positions of the requested sites,
probes or regions. Identifiers, if present, can be obtained using the
names method. Strand information is also
included when applicable. Any additional annotation is stored as metadata in the respective
Probe, site or region annotation table. If the specified type refers to control probes, the returned value is
data.frame listing all respective control probes. Otherwise, this function returns an object of type
GRangesList - a list of consistent
GRanges objects, one per chromosome.
