edit.nb {spdep} | R Documentation |
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
.
