Yes. I expected plot.histogram() was something that no-one ever calls directly (and I still expect that!), and I expected hist() to pass everything on to plot.histogram(). I guess I think the most elegant design would be to remove all plotting functionality from hist(), and put all arguments into plot.histogram(). Or make histogram objects store everything. But, I expect you can't changed this now, for compatability / user familiarity reasons... > AndrewC> Perhaps it might be helpful to document in the > AndrewC> hist() help page which attributes are stored in the > AndrewC> hist() object. > you mean the 'histogram' object.

R's introspection capabilities are a little mysterious to me. The missing() docs mention that it should be improved in future. That might be a better long-term solution?
