Description Author(s) References See Also

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 `???.point`

, `???.line`

, and
`???.polygon`

, where '`???`

' is either `hal`

, `bas`

, `grts`

,
`sss`

, or `srs`

. For simplicity, an S4 generic,
`sdraw`

, is provided to handle all combinations of sample and frame types
(see `sdraw`

).
