CARBayes (version 4.2)

highlight.borders: Creates a SpatialPoints object identifying a subset of borders between neighbouring areas.

Description

Creates a SpatialPoints object identifying a subset of borders between neighbouring areas, which allows them to be overlayed on a map. An example is given in the vignette accompanying this package.

Usage

highlight.borders(border.locations, spdata)

Arguments

border.locations
A K by K matrix, where K is the number of areas, containing 3 distinct values: NA for non-neighbouring areas; 0 for borders between neighbouring areas to be highlighted on a map; and 1 for borders between neighbouring areas not to be highlighted on a m
spdata
The 'SpatialPolygonsDataFrame' object used for plotting the data and creating the original neighbourhood matrix W.

Value

  • A `SpatialPoints' object from the `sp' package, which contains the vertices of all the borders to be highlighted on the map. The mapping can be done using the `spplot()' function, see the vignette accompanying this package for an example.
