Package: pathroutr 0.2.1

pathroutr: An R Package for (Re-)Routing Paths Around Barriers

The `pathroutr` package aims to provide a set of tools for routing marine animal tracks around land barriers based on the shortest path through a visibility graph network. The foundation of the package is a graph network created from a Delaunay Triangle mesh created from the vertices of land polygons within the study area. Any network edges that cross or fall completely within the land (barrier) polygons are removed.
