SDraw provides a set of R functions that draw Halton-Lattice samples (HAL), Balanced-Acceptance-Samples (BAS), Generalized-Random-Tessellation-Stratified (GRTS) samples, Simple-Systematic-Samples (SSS), and Simple-Random-Samples (SRS). The types of input frames accepted are points (0-D, finite), lines (1-D, infinite), or polygons (2-D, infinite).

The work-horse functions are named
???.polygon, where '
???' is either
srs. For simplicity, an S4 generic,
sdraw, is provided to handle all combinations of sample and frame types
