Are you after this?
last_plot() + opts(aspect.ratio=1)
Also, see https://github.com/hadley/ggplot2/wiki/Themes for some
settings re: plot margins.

Of course the other elements like axis and legend will make the over all plot to not be square but I do not care as the blue and red region forms a square.
