A package providing methods for cubature (numerical integration)
over polygonal domains.
Currently, four cubature methods are implemented:
the two-dimensional midpoint rule (a simple wrapper around
spatstat::as.im.function), the product Gauss cubature proposed
by Sommariva and Vianello (2007), an adaptive cubature for
isotropic functions via line integrate() along the boundary,
and quasi-exact methods specific to the integration of the
bivariate Gaussian density over polygonal and circular domains.
For cubature over simple hypercubes, the
packages cubature and R2Cuba are more appropriate.

A package providing methods for cubature (numerical integration)
over polygonal domains.
Currently, four cubature methods are implemented:
the two-dimensional midpoint rule as a simple wrapper around
as.im.function() from package spatstat (Baddeley and Turner, 2005),
the product Gauss cubature by Sommariva and Vianello (2007),
an adaptive cubature for isotropic functions via line integrate()
along the boundary (Meyer and Held, 2014),
and quasi-exact methods specific to the integration of the
bivariate Gaussian density over polygonal and circular domains
(based on formulae from the Abramowitz and Stegun (1972) handbook).
For cubature over simple hypercubes, the packages cubature and
R2Cuba are more appropriate.
