R help - Sep 2008 - multiple plots - editing ggplot2 plot

Hi All,

I am trying to build a composite plot, with multiple categories, using
ggplot2.

In principle, it could be done using facetting, but I do not seem to be able
to get past the defaults, so I try building each plot separately, then
putting them all together using frameGrob and placeGrob.
For this, I need to know how to:
1) format the legend with a different layout (e.g 2 rows by 2 columns,
rather than using the vertical orientation only;
2) draw the numbers on top of the bars (the issue is locating the bars, of
course);
3) extract the definition of the axes (scales, with breaks and labels) from
the individual plots

I am attaching an image describing what I would like to achieve. The quality
is low, to avoid consuming too much of your bandwidth.
I would appreciate any pointers.
Thanks,
Pedro http://www.nabble.com/file/p19703615/MultiPlotDesign.jpg

Could you post the data that you are using?  You should be able to do
most of that without any customisation of ggplot2.

Hi Hadley,

Thanks for the quick reply.
Well, if I could do it directly in ggplot, even better.
My data is below (from "dump").
I calculate the bar heights previously, now I just want to plot them, with
fixed fill colours (to make sure they match other plots I use). Thanks
again,
Pedro
