r-cran-polycub binary package in Ubuntu Trusty i386

 PolyCub is a GNU R 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.
