This document illustrates functionalities of sp and rgeos libraries using spatial data provided by DANE and DIVA_GIS.

This document illustrates how to create a spatial polygon when you have pairs of coordinates corresponding to its vertices.

This document illustrates how to describe the dispersion of a set of points on a Cartesian plane using both the standard distance deviation (SDD) and the standard deviational ellipse (SDE).

This is an illustration of reading spatial objects from a shapefile and joining attributes from a table.

This is an illustration of generation of sampling sites using the sp package. Much of the text and R code has been taken from California Soil Resource Lab at UC Davis.
