ppmData: Quasirandom quardature scheme using dirichlet tesselation for spatial Poisson point process models

This package generates a set of quasi-random points for a quadrature scheme, we calculate each points weights using a dirichlet tesselation (voronoi) algorithm. The resulting object can be used in existing single and multiple species models in order to extend them to Point Processes.
