A collection of functions for computing centrographic
statistics (e.g., standard distance, standard deviation
ellipse, standard deviation box) for observations taken at
point locations. Separate plotting functions have been
developed for each measure. Users interested in writing results
to ESRI shapefiles can do so by using results from 'aspace'
functions as inputs to the convert.to.shapefile() and
write.shapefile() functions in the 'shapefiles' library. We intend to
provide 'terra' integration for geographic data in a future release.
The 'aspace' package was originally conceived to aid in the analysis of
spatial patterns of travel behaviour (see Buliung and Remmel 2008
