[R] qqnorm with histogram?

[Spencer Graves]

       Does a function exist that combines a normal probability plot 
with a histogram and maybe a density estimate on the same plot?


       I'm revising the Wikipedia article on "Normal probability plot", 
and I think it would be good to provide examples of this.


       Thanks,
       Spencer


p.s.  Please reply also with suggestions for how to improve that 
Wikipedia article if you feel so inclined.
