aspace-package {aspace} | R Documentation |
A collection of functions for computing centrographic satistics (e.g., standard distance, standard deviation ellipse), and minimum convex polygons (MCP) from point data. A tool is also provided for converting geometric objects associated with the centrographic statistics, and MCPs into ESRI Shapefiles. This library was initially conceived to aid in the analysis of spatial patterns of travel behaviour (see Buliung and Kanaroglou, 2006).
