You can get something close with 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()
