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

1
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 map.

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.
