title: 'phinterval: Set Operations on Time Intervals'
version: 1.0.0.9000
doi: 10.32614/CRAN.package.phinterval
abstract: Implements the phinterval vector class for representing time spans that
  may contain gaps (disjoint intervals) or be empty. This class generalizes the 'lubridate'
  package's interval class to support vectorized set operations (intersection, union,
  difference, complement) that always return a valid time span, even when disjoint
  or empty intervals are created.
