Yes.   But you don't even need another package.  Thanks to 
John Fox, there's
     rstudent()
     rstandard()
etc, even in the 'stats' package, with methods for "lm" and for 
"glm" objects.

And now, in R-devel (2.4.0-to-be),
   help.search("studentized")
will show the 'influence.measures' help page which contains rstudent().
