calculate_geodesic_distances: Calculate geodesic distances between cells in a trajectory

Description

Will calculate geodesic distances between cells within a trajectory. To speed things up, only the distances with a set of waypoint cells are calculated.

Usage

calculate_geodesic_distances(
  trajectory,
  waypoint_cells = NULL,
  waypoint_milestone_percentages = NULL,
  directed = FALSE
)
compute_tented_geodesic_distances(
  trajectory,
  waypoint_cells = NULL,
  waypoint_milestone_percentages = NULL
)

Arguments

trajectory

The trajectory as created by infer_trajectory() or add_trajectory()

waypoint_cells

A vector of waypoint cells. Only the geodesic distances between waypoint cells and all other cells will be calculated.

waypoint_milestone_percentages

The milestone percentages of non-cell waypoints, containing waypoint_id, milestone_id and percentage columns

directed

Take into account the directions of the milestone edges. The cells that cannot be reached from a particular waypoint will have distance infinity. You can also give a character, if it is "forward" it will look forward, if it is "reverse" it will look in the reversed direction

Value

A matrix containing geodesic distances between each waypoint cell (rows) and cell (columns)

Details

The geodesic distance takes into account the length of an edge regions of delayed commitment.

Examples

# NOT RUN {
geodesic_distances <- calculate_geodesic_distances(example_trajectory)
geodesic_distances[1:10, 1:10]

# }
