Generation of Sample Site Locations [sp package for R]

Premise
Setting up sampling designs is a non-trivial aspect to any field experiment that includes a spatial component. The sp package for R provides a simple framework for generating point sampling schemes based on region-defining features (lines or polygons) and a sampling type (regular spacing, non-aligned, random, random-stratified, hexagonal grid, etc.). The rgdal package provides a set of functions for importing/exporting common vector data formats. This example demonstrates simple import/export, iterating over sp objects, and reconstituting new objects from lists of objects. A more complex sampling scheme is demonstrated here.
