margins=TRUE still broken in 0.8.9?

[Jeff]

I want to confirm that margins=TRUE is still broken in ggplot2 0.8.9.
I get an error message for this:

p <- qplot(displ, hwy, data = mpg) + geom_point(); p + facet_grid(cyl
~ drv, margins = TRUE)

Error in class(output[[var]]) <- class(value) :
cannot set class to "array" unless the dimension attribute has
length > 0

Is there a workaround other than one involving pushViewport()? Thanks!

Yes, still broken, sorry. You could work around it by using the
add_margins function from plyr to add the margins yourself.
