[R] Potential-Residual Plot (Hadi, 1994)

[Christoph Lehmann]

Hi
Does anybody know, whether the Potential-Residual Plot, suggested by
Hadi (1994) has already been implemented in R? 

Hadi, A. S. (1992), "A New Measure of Overall Potential Influence in
Linear Regression," Computational Statistics & Data Analysis, 14, 1-27.
(The proposed Potential-Residual Plot has been implemented in Data Desk)

Thanks a lot for a hint

Cheers
Christoph
