Hi Hadley,

Thanks. I did this already, indeed, but the issue is that then I get a gTree object, not a ggplot object (I believe the option of building all objects off-screen and then printing the plot in whichever device we choose is the best option. That is indeed why I like your ggplot concept so much). I can live with that, of course, but there is a more fundamental issue here: why do axes have only ticks, and labels, and not line, as slots/children? (I know it is also the underlying option in grid, but I cannot see the logic behind that...).

Cheers,
Pedro
