[R] Multiple stacked barplots on the same graph?

[Stéphane CRUVEILLER]

Dear R-Users,

I would like to know whether it is possible to draw several
stacked barplots (i.e. side by side on the same sheet)...


my data look like :

                            Cond1  Cond1' Cond2   Cond2'
Compartment 1    11,81    2,05    12,49    0,70   
Compartment 2     10,51    1,98    13,56    0,85
Compartment 3     1,95    0,63    2,81    0,22  
Compartment 4     2,08    0,17    3,13    0,06   
Compartment 5     2,51    0,20    4,58    0,03

ps: Cond1' values should be stacked on Cond1, Cond2' on Cond 2 and so 
on... and series 1 and 2
should be side by side for each compartement....

Thanks for any help.

Stéphane.
