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 )An "Intervals" or "Intervals_full" object.
Should validObject be called before passing to
compiled code? Also see interval_overlap.
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.
See interval_union, which is really just concatenates its
arguments and then calls reduce.
