edit.nb.Rd
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
.
This method relies on direct contact with the graphics device. Do not use in RStudio.
# S3 method for nb
edit(name, coords, polys=NULL, ..., use_region.id=FALSE)
an object of class nb
matrix of region point coordinates; if missing and polys= inherits from SpatialPolygons
, the label points of that object are used
if polygon boundaries supplied, will be used as background; must inherit from SpatialPolygons
further arguments passed to or from other methods
default FALSE
, in identify
use 1-based observation numbers, otherwise use the nb
region.id
attribute values
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.
