%description
Provides classes and functions to calculate various distance measures and
routes in heterogeneous geographic spaces represented as grids. The
package implements measures to model dispersal histories first presented
by van Etten and Hijmans (2010) <doi:10.1371/journal.pone.0012060>.
Least-cost distances as well as more complex distances based on
(constrained) random walks can be calculated. The distances implemented in
the package are used in geographical genetics, accessibility indicators,
and may also have applications in other fields of geospatial analysis.
