Hi Ross, In brief, you can use ggopt(aspect.ratio = 1) or p$aspect.ratio <- 1 to set the aspect ratio for all plots, or for a single plot respectively. There are a few example of this at http://had.co.nz/ggplot2/coord_equal.html
I am also preparing a chapter for the ggplot book which will discuss this, as well as more general details of customising absolutely every aspect of ggplot2 with grid. I hope to have this out by the end of the week - I'll probably send another anouncement to R packages when this is ready. You should be able to start using ggplot2 with very little effort, especially if you have been using qplot a lot.
