SDraw-package: Selection of spatially balanced samples.

In tmcd82070/SDraw: Spatially Balanced Samples of Spatial Objects

Description

SDraw provides a set of R functions that draw Halton Iterative Partitioning samples (HIP), 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
Type:	Package
License:	GNU General Public License
Imports:	spsurvey, utils, rgdal, rgeos, graphics, methods, deldir, OpenStreetMap, stats, covr
Depends:	sp

The work-horse functions are named ???.point, ???.line, and ???.polygon, where '???' is either hip, bas, grts, sss, or srs. For simplicity, an S4 generic, sdraw, is provided to handle all combinations of sample and frame types (see sdraw).
