Function spatstat.geom::owin() creates an observation window in the two-dimensional plane (owin.object), i.e., an R object of S3 class 'owin'. Package groupedHyperframe (v0.3.0.20251020) does not implements any S3 method dispatch to the class 'owin', in addition to the existing S3 method dispatches spatstat.geom::*.owin (v3.6.0.3, Listing 22.1),
