SDraw-package: Selection of spatially balanced samples.

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).

Package: SDraw

Depends: sp

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).
