R devel - Aug 2008 - wishlist: par(ann=FALSE) applied to hist?

par(ann=FALSE) appears to have no effect on
hist.default; it would be nice if it did ...
(boxplot, which plots via bxp, which calls
internal do_title, does -- in a quick search
I can't figure out where the value of ann
takes effect ...)

   thanks

>From the ?par:
      'ann' If set to 'FALSE', high-level plotting functions
calling
           'plot.default' do not annotate the plots they produce with
           axis titles and overall titles.  The default is to do
           annotation.

So strictly this is correct, as plot.histogram does not call plot.default. 
The par is only used at R level, as a default for an argument in 
plot.default and never as an in-line parameter.

So I think what you are asking for is a 'ann' argument to
plot.histogram,
which would then be passed down from hist().  The only issue then is if 
par("ann") should set the default, and the current documentation says
not.

Does that meet your needs?
