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
).
