If this is correct, there is a worked example in V&R's MASS 4 (the book) on page 204 with respect to the use of the polr() function in MASS (the package.) An alternative is in Frank's Design package, where using ?residuals.lrm will provide some examples, including diagnostic plots. HTH, Marc Schwartz
