neighborhoodEuclidean: Compute Euclidean path pump neighborhoods.

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

Compute Euclidean path pump neighborhoods.

Description

Plots star graph from pump to its cases.

Usage

neighborhoodEuclidean(pump.select = NULL, vestry = FALSE,
  case.set = "observed", case.select = "address", latlong = FALSE,
  location = "nominal", brute.force = FALSE, multi.core = TRUE,
  dev.mode = FALSE)

Arguments

pump.select	Numeric. Vector of numeric pump IDs to define pump neighborhoods (i.e., the "population"). Negative selection possible. NULL selects all pumps.
vestry	Logical. TRUE uses the 14 pumps from the Vestry Report. FALSE uses the 13 in the original map.
case.set	Character. "observed" or "expected".
case.select	Character. Fatalities: "all" or "address".
latlong	Logical. Longitude and latitude coordinates
location	Character. "nominal", "anchor" or "orthogonal".
brute.force	Logical. For latlong = FALSE. TRUE computes nearest pump for each case. FALSE uses Voronoi cells as shortcut.
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.
dev.mode	Logical. Development mode uses parallel::parLapply().

Value

An R list.
