R help - May 2009 - Labeling barplot bars by multiple factors

I want to plot quantitative data as a function of three two-level factors.
How do I group the bars on a barplot by level through labeling and spacing?

I'm thinking of. Also, I'm pretty sure that I want a barplot, but there
may
be something better.

You can get something close with ggplot2:

library(ggplot2)
my_data = expand.grid(
	A = factor(c('A1','A2'))
	, B = factor(c('B1','B2'))
	, C = factor(c('C1','C2'))
)
my_data$DV = rnorm(8,mean=10,sd=1)
p = ggplot()
p = p + layer(
	geom = 'bar'
	, stat = 'identity'
	, data = my_data
	, mapping = aes(
		x = C
		, y = DV
		, fill = B
	)
	, position = 'dodge'
)
p = p + facet_grid(
	A ~ .
)
p = p + coord_flip()
print(p)

Hi Tom,
You may find that the hierobarp function in the plotrix package will do 
what you want.

Ah, that makes sense. But now another two issues have arisen.

Firstly, the error bars look like confidence intervals, and I'm pretty
sure that they are but does some document verify this? I suppose I
could check the code too.

Secondly, I just read about how dynamite plots should be avoided. It's
quite easy to turn the dynamite plots into dot plots with Inkscape,
but is there an equivalent function that generates _hierarchical_ dot
plots?
