Kjetil, did I forget to tell you that your above "hack" has made it 
(after a bit of modification) into
R 1.2 [due on Dec 15] ?

Here is the NEWS entry (under "NEW FEATURES")

    o	hist() now returns a "histogram" object and calls the new
	function plot.histogram() for plotting.
	It now also allows character labels.


Thanks for your contribution!
