edit.nb: Interactive editing of neighbours lists

Description

The function provides simple interactive editing of neighbours lists to allow unneeded links to be deleted, and missing links to be inserted. It uses identify to pick the endpoints of the link to be deleted or added, and asks for confirmation before committing. If the result is not assigned to a new object, the editing will be lost - as in edit.

Usage

edit.nb(name, coords, polys=NULL, bbs=NULL, ...)

Arguments

name
an object of class nb
coords
matrix of region point coordinates
polys
if polygon boundaries supplied, will be used as background
bbs
bounding boxes for polygons
...
further arguments passed to or from other methods

Value

  • The function returns an object of class nb with the edited list of integer vectors containing neighbour region number ids, with added attributes tallying the added and deleted links.
