R help - May 2011 - multiple mosaic plots layout

I would like to display multiple mosaic plots from vcd (not defined by a model
but derived from different data sets)
side by side.
Neither par(mfrow=...)
nor layout seem to allow to arrange multiple mosaic plots in a grid.
Is there an easy way of arranging mosaics in a grid?

Unfortunately, it seems that vcd doesn't return grobs but draws
directly to the device, which prevents a concise solution. You could
try the following,

library(gridExtra)
library(vcd)
data("Titanic")

p = grid.grabExpr(mosaic(Titanic))
grid.arrange(p, p, p, ncol=2)

Or, more versatile but also more verbose,

pushViewport(...)
mosaic(...)
upViewport()
pushViewport(...)
mosaic(...)
upViewport()
etc..

HTH,

baptiste
