Pairwise wind distances between points
least_cost_distance.RdCalculate pairwise wind cost-distances (e.g. travel times) or flow rates (the inverse of cost-distances) among a set of sites, using the least cost path algorithm. This function is a wrapper around costDistance.
Arguments
- graph
A wind_graph.
- sites
A two-column matrix of point coordinates.
- adjust
Whether to scale results to correct for discrepancies between point-to-point distances and cell-to-cell distances. Default is TRUE.
- rate
Whether to return values as "rates" instead of the default "cost distances". Rates are the inverse of cost distances, representing flow rather than travel time.
