potential package provides functions to compute potential models as defined by John Q. Stewart. Several options are available to customize the models, for example it is possible to refine the distance friction functions or to use custom distance matrices. Some functions use parallelization to improve their efficiency.
The aim of
potential is to replace potential-related functions of the
SpatialPosition was built to compute 3 spatial position models (Stewart potentials, Reilly catchment areas, Huff catchment areas) in a time where
sf was not published yet (May 2015).
potential functions use a simplified interface and are more efficient than their counterpart in
SpatialPostion. My recommendation to
SpatialPositon users is thus to switch to
potential for the computation of potentials.
