⚠️There's a newer version (0.9.0) of this package.Take me there.
polyCub (version 0.4-2)
Cubature over Polygonal Domains
Description
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.
