[R] Histogram Bar Spacing or Border Width

[Prof Brian Ripley]

A histogram is a density estimate (at least as defined in the Encyclopedia 
of Statistics Sciences, if not in many US Universities).  It is an area, 
not a series of unrelated bars, so it makes no sense to have spaces 
between the subareas.

Unfortunately, hist() will also produce barplots of counts.
