In general, "Intervals"
and
"Intervals_full"
objects may be redundant, the
intervals they contain may be in arbitrary order, and they may contain
non-informative intervals for which one or both endpoints are
NA
. The reduce
function re-represents the underlying
subsets of the integers or the real line in the unique, minimal form,
removing intervals with NA
endpoints (with warning).
# S4 method for Intervals_virtual
reduce( x, check_valid = TRUE )
A single object of appropriate class, compactly representing the
union of all intervals in x
. All intervals in reduce(x)
have numeric (i.e., not NA
) endpoints.
An "Intervals"
or "Intervals_full"
object.
Should validObject
be called before passing to
compiled code? Also see interval_overlap
.
See interval_union
, which is really just concatenates its
arguments and then calls reduce
.
