| RangesMapping-class {IRanges} | R Documentation |
The map generic converts a set of ranges to the equivalent
ranges on another sequence, through some sort of alignment between
sequences, and outputs a RangesMapping object. There are three
primary components of that object: the transformed ranges, the
space (destination sequence) for the ranges, and the
hits, a Hits object of the same length
that matches each input range to a destination sequence (useful when
the alignment is one/many to many). The pmap function is
simpler: it treats the two inputs as parallel vectors, maps each input
range via the corresponding alignment, and returns the mapped
ranges. There is one result per input element, instead of the
many-to-many result from map.

Arguments to pass to methods |
A RangesMapping object, as documented here.
RangesMapping Accessorsranges(x): Gets the mapped ranges.
space(x): Gets the destination spaces (sequence
names).
hits(x): Gets the matching between the input ranges
and the destination sequences (of which there may be more than
one).
dim(x): Same as dim(hits(x)).
length(x): Same as length(hits(x)).
subjectHits(x): Same as subjectHits(hits(x)).
queryHits(x): Same as queryHits(hits(x)).
RangesMapping Coercionas(from, "RangedData"): Converts
a RangesMapping into
a RangedData. The ranges/space
in the RangedData are the ranges/space
of from, and the values result from the coercion of
the hits to a DataFrame.

Methods on the generic map, which generates an instance of
this class, are defined in other packages, like GenomicRanges.
