[R] Barplot() questions

[Mike Prager]

Using R 1.6.1 on Windows 2000.  As always, a big THANK YOU to the R team.

(1) Can the legend position be specified in barplot()?    Right now, we are 
doing this with a separate call to legend().

(2) For a stacked bar, we wish to show both positive and negative values, 
rather than taking an algebraic sum.  Right now, negative values in a stack 
are plotted starting from the top of any summed positive values.  Not sure 
if this is a feature or a bug (as the negative values can overlay the 
positive and vice versa).
