[R] using color coded colorbars for bar plots

Hello R Fundi,

The poetic title of this post is a request for help in regard to a
"simple" plotting question.  
I have displayed the mean observations of a series variables using
barplot().  On the same figure I have colored the bars to represent the
Standard deviation of each variable using color.scale().  Now I wish to
add a graduated colorbar (legend) that corresponds to the colors
representing the standard devitation.  Simple.  Or so it seemed.  Has
anyone attempted to do this before?  

Thanks for your time.

Jim Dell
