addNeighborhoodCases: Add observed cases by neighborhood.

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

Add observed cases by neighborhood.

Description

Add cases to a plot as "address" or "fatalities" and as points or IDs.

Usage

addNeighborhoodCases(pump.subset = NULL, pump.select = NULL,
  metric = "walking", type = "stack.base", token = "point",
  text.size = 0.5, pch = 16, point.size = 0.5, vestry = FALSE,
  weighted = TRUE, color = NULL, case.location = "nominal",
  alpha.level = 0.5, multi.core = TRUE)

Arguments

pump.subset	Numeric. Vector of numeric pump IDs to subset from the neighborhoods defined by pump.select. Negative selection possible. NULL uses all pumps in pump.select.
pump.select	Numeric. Numeric vector of pump IDs that define which pump neighborhoods to consider (i.e., specify the "population"). Negative selection possible. NULL selects all pumps.
metric	Character. Type of neighborhood: "euclidean" or "walking".
type	Character. Type of case: "stack.base" (base of stack), or "stack" (entire stack). For observed = TRUE.
token	Character. Type of token to plot: "point" or "id".
text.size	Numeric. Size of case ID text.
pch	Numeric.
point.size	Numeric.
vestry	Logical. TRUE uses the 14 pumps from the Vestry Report. FALSE uses the 13 in the original map.
weighted	Logical. TRUE computes shortest walking path weighted by road length. FALSE computes shortest walking path in terms of the number of nodes.
color	Character. Use a single color for all paths. NULL uses neighborhood colors defined by snowColors().
case.location	Character. For metric = "euclidean": "address" uses ortho.proj; "nominal" uses fatalities.
alpha.level	Numeric. Alpha level transparency for area plot: a value in [0, 1].
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.
