[R] two histograms in the same graph

[David Daniel]

You might look at the method histbackback (back-to-back histograms) in  
package Hmisc.  At the time I looked at this package about a year ago,  
I could not get it working on my Mac, so I don't actually know what  
the results look like, but I have created them before in XLispStat and  
found them useful.  From posts I've seen more recently, I believe that  
whatever the problem I was encountering previously on the Mac has been  
resolved.
