Dear Didier,

This is apparently a small bug in the function edit.nb from the spdep package.
To fix it, type fix(edit.nb) and then replace :
  if (!inherits(x, "nb"))
        stop("not a neighbours list")
with
 if (!inherits(nb, "nb"))
        stop("not a neighbours list")

After this you can just use edit.nb as expected.
I'll email Roger Bivand to bug-report, it should be fixed soon.

Best,

Thibaut.
