R help - Dec 2009 - Multiple grouping on the X axis.

I am trying to plot data with multiple logical and physical groups using
R.  Below is a sample of the kind of data I am working with and the desired
output.  We have a jmp script that can do the same thing, but at ~$200 a
year the licensing is counterproductive.  Thanks for any help.

Data input: Loaded from a CSV file.
Physical_1 Logical_1 Logical_2 Data_1 Data_2
x               Y           Z2          54       56
x               Y2         Z2          53       55
x               Y3         Z2          52       54
x2             Y           Z            60       58
x2             Y2         Z            59       57
x2             Y3         Z            58       56
x3             Y           Z            56       53
x3             Y2         Z            55       52
x3             Y3         Z            54       51
x4             Y           Z2          52       55
x4             Y2         Z2           51       54
x4             Y3         Z2           50       53


I need the graph to be grouped as follows:
-------------------------------------
|Y|Y2|Y3|Y|Y2|Y3|Y|Y2|Y3|Y|Y2|Y3|
-------------------------------------
|     X    |  X4      |  X2       |  X3      |
-------------------------------------
|       Z               |        Z2             |
-------------------------------------

   Again, any help would be appreciated.

Hi Munin,
Look at hierobarp in the plotrix package. The current version doesn't 
have the recently programmed option to pass a list of arrays with the 
values, so if you want this capability, I will email the new code.
