[R] boxplot question

Using the example in the boxplot documentation:
data(InsectSprays)
I'd like to create two boxplots (one on top of the other) the
first showing the stats for the full data-set and the second
showing the stats for a subset. For the sake of example assume
I want to show in the bottom plot the dist for only points with
count>6.
I set it up as follows:
layout(matrix(c(1,2,),2,1))
boxplot(count ~ spray, data = InsectSprays)
boxplot(count ~ spray, data = InsectSprays, subset=count>6)
However, notice the bottom boxplot's x-axis is different from
the upper boxplot's x-axis. This is because E isn't represented
in the subset.
How can I create the bottom boxplot such that E is included but
empty, allowing top and bottom plots to line-up for comparison?
