Description

Add Voronoi cells.

Usage

addVoronoi(pump.select = NULL, vestry = FALSE, case.location = "nominal",
  color = "black", line.type = "solid", line.width = 1,
  latlong = FALSE)

Arguments

pump.select	Numeric. Default is NULL; all pumps are used. Otherwise, selection by a vector of numeric IDs: 1 to 13 for pumps; 1 to 14 for pumps.vestry. Exclusion (negative selection) is possible (e.g., -6).
vestry	Logical. FALSE for original 13 pumps. TRUE for 14 pumps in Vestry Report.
case.location	Character. For observed = FALSE: "address" or "nominal". "nominal" is the x-y coordinates of regular.cases.
color	Character. Color of cell edges.
line.type	Character. Type of line for cell edges: lty.
line.width	Numeric. Width of cell edges: lwd.
latlong	Logical. Use estimated longitude and latitude.
