In cholera: Amend, Augment and Aid Analysis of John Snow's Cholera Map

Plot walking path to nearest pump (prototype).

Description

Plot walking path to nearest pump (prototype).

Usage

latlongWalkingPath(case = 1, destination = NULL, vestry = FALSE,
  weighted = TRUE, distance.unit = "meter", time.unit = "second",
  walking.speed = 5, multi.core = TRUE)

Arguments

case	Numeric.
destination	Numeric. Pump ID.
vestry	Logical. TRUE uses the 14 pumps from the map in the Vestry Report. FALSE uses the 13 pumps from the original map.
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.
multi.core	Logical or Numeric. TRUE uses parallel::detectCores(). FALSE uses one, single core. You can also specify the number logical cores. See vignette("Parallelization") for details.
