People who want (fairly) precise
comparisons of the Cook's statistics can still use the present
plot #4, perhaps as a follow-up to the new plot #5.
It would be possible to label the Cookwise most extreme
points with the actual values (to perhaps 2sig figures, i.e.,
labeling on both sides of suc

whatever form of labeling best suits their case, their imaginative
skills and their coding skills.

rs is not
strictly necessary, but it does avert complaints from plot() when they
are passed as unnamed parameters.
(I foreshadowed this when I submitted problem #6327, and offered a fix
