Add walking path from case/landmark to nearest or selected pump. (prototype)

Description

Add walking path from case/landmark to nearest or selected pump. (prototype)

Usage

addWalkingPathB(origin = 1, destination = NULL, type = "case-pump",
  vestry = FALSE, latlong = FALSE, weighted = TRUE,
  distance.unit = "meter", time.unit = "second", walking.speed = 5,
  include.landmarks = TRUE, mileposts = TRUE, milepost.unit = "distance",
  milepost.interval = NULL, alpha.level = 1, ...)

Arguments

origin	Numeric. Vector of origin(s) (numeric or case/landmark name).
destination	Numeric. Vector of destination(s) (numeric or landmark/pump name).
type	Character. Path case to pump. FALSE is all other combinations of cases, landmarks and pumps.
vestry	Logical. TRUE uses the 14 pumps from the map in the Vestry Report. FALSE uses the 13 pumps from the original map.
latlong	Logical.
weighted	Logical. TRUE computes shortest path in terms of road length. FALSE computes shortest path in terms of the number of nodes.
distance.unit	Character. Unit of distance: "meter" or "yard".
time.unit	Character. "hour", "minute", or "second".
walking.speed	Numeric. Walking speed in km/hr.
include.landmarks	Logical. Include landmarks as cases.
mileposts	Logical. Plot mile/time posts.
milepost.unit	Character. "distance" or "time".
milepost.interval	Numeric. Mile post interval unit of distance (yard or meter) or unit of time (seconds).
alpha.level	Numeric. Alpha level transparency for path: a value in [0, 1].
...	Additional plotting parameters.
