R help - Jul 2008 - layout is to xyplot as ??? is to qplot

Playing with ggplot, something I'd promised myself I'd get around to.
I've
the following scenario:

library(lattice)
library(ggplot2)

myData <- data.frame(
	x = rnorm(100),
	y = rnorm(100),
	group = 1:4
)

xyplot(y ~ x | factor(group), data = myData, layout = c(2, 2))

qplot(x, y, facets = ~ group, data = myData) 



In this code the lattice example gives me a 2x2 layout, whereas the ggplot
example gives me a 1x4 layout, as per the facets specification. Can I mimic
the effect of the layout parameter in xyplot inside qplot? Apologies if I've
missed an obvious help-page somewhere!

Thanks in advance,

Not yet, but I'm working on that code at the moment, and it should be
(fingers crossed) included in the next ggplot2 release.  Currently,
ggplot assumes you want a grid of facets defined by separate variables
in the x and y dimensions.
