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...).
