plot.movecost_rank

Returns a ggplot object showing, depending on <code>type</code>, the ranked paths
over the terrain (<code>"map"</code>, default), the same paths drawn over the
least-cost corridor between the two locations (<code>"corridor"</code>, the
equivalent of movecost &lt;= 2.x's <code>use.corr</code>), or a bubble chart of path
length against rank with bubble size proportional to cost (<code>"chart"</code>,
the equivalent of movecost &lt;= 2.x's <code>add.chart</code>). No manual data
assembly is required for any of them.

Provides the facility to calculate non-isotropic accumulated cost surfaces, least-cost paths, least-cost corridors, least-cost networks, ranked alternative paths, cost allocation and cost boundaries, using a number of human-movement-related cost functions that can be selected by the user. The package is built around a compute-once design: a single cost surface object is created first and then reused by every analysis function, avoiding redundant computation. Visualisation is fully decoupled from computation and is provided through 'ggplot2' methods that can be invoked, customised, and re-invoked at any time without re-running any analysis. It just requires a Digital Terrain Model, a start location and (optionally) destination locations. See Alberti (2019) <doi:10.1016/j.softx.2019.100331>.
