Description Usage Arguments Value Author(s) See Also Examples
This function calculates the distance between a set of geographical coordinates and generates a matrix containing the distances between each of the points. In development.
1 | GenerateLeastCostDistance(sPointsFile,sTransition)
|
sPointsFile |
a dataframe containing the |
sTransition |
a Transition object generated from a RasterLayer using the gdistance R package |
a 2x2 matrix containing the pairwise direct DISTANCE
between each LOCATION
minus the detection RADIUS
. Distances are returned in kilometers
