[R-sig-ME] standardized residuals

[Michael Larkin]

Anyone use the standardized residuals function in R?  It is called stdres   

I can't get it to work.  It tells me there is no documentation for stdres.
I am assuming there is a package that I need to load.  I looked at the list
of packages and I can't find one for stdres.  It must be bundled in some
package.    

Any advice on how I can get stdres to work would be greatly appreciated.
