a polygonal domain. The following classes are supported: "owin" from package spatstat, "gpc.poly" from rgeos (or gpclib), as well as "SpatialPolygons", "Polygons", and "Polygon" from package sp. (For these classes, polyCub knows how to get an xylist.)

a two-dimensional real-valued function to be integrated over polyregion. As its first argument it must take a coordinate matrix, i.e., a numeric matrix with two columns, and it must return a numeric vector of length the number of coordinates.
For the "exact.Gauss" method, f is ignored since it is specific to the bivariate normal density.

choose one of the implemented cubature methods (partial argument matching is applied), see help("polyCub-package") for an overview. Defaults to using product Gauss cubature implemented in polyCub.SV.

arguments of f or of the specific method.

logical indicating if an illustrative plot of the numerical integration should be produced.
