[R-SIG-Finance] Standard deviation and plots

[Peter Carl]

There's a good example of such an overlay at:

http://zoonek2.free.fr/UNIX/48_R/03.html

Look for a chart called "Third moment (skewness)".  The example shows 
how to calculate dimensions and draw a vertical line segment overlaid 
on the histogram.  Although he isn't doing exactly what you're looking 
for, the code could be easily modified for your use.   

There's a lot of other good stuff there, as well.

Enjoy,
