R help - Feb 2010 - Boxplots with similar number of classes....

I have four boxplots, stacked on top of one another (vertically). There are
five classes that the continuous variable is set against. The problem I have
is the data for the second boxplot only contains values for four of the five
classes.

I would like to include the space in this graph so there is a continuity for
all of the boxplots, in terms of number of classes. I would include a set of
zeroes, but they are omitted from all graphs for a number of reasons.
Basically is there anyway to add in that class that isn't being plotted for
this particular boxplot?

TIA- Matt http://n4.nabble.com/file/n1565299/b1help.jpg

Run the fourth example in help(boxplot) and then run this:

 > OrchardSprays$treatment <- factor(OrchardSprays$treatment, levels=  
LETTERS[1:9])
 > rb <- boxplot(decrease ~ treatment, data = OrchardSprays,  
col="bisque")
 > title("Comparing boxplot()s and non-robust mean +/- SD")
