pack produces a
of the same ranges grouped and re-ordered.
A numeric specifying the max length allowed for ranges in
A numeric specifying the max length allowed between ranges in
Arguments passed to other methods.
pack method attempts to re-package ranges in optimal
form for extracting data from files. Ranges are not modified (made
shorter or longer) but re-ordered and / or re-grouped according
to the following criteria.
order: Ranges are ordered by genomic position within chromosomes.
distance: Ranges separted by a distance greater than
inter_range_len are packed in groups around
the gap separating the distant ranges.
length: Ranges longer than
range_len are packed
‘individually’ (i.e., retrived from the file as a single
range vs grouped with other ranges).
Returns a logical indicating if the ranges in
x are packed.
x must be a
unpack for unpacking the result obtained
with ‘packed’ ranges.
