[R] ggplot2 to create a "square" plot

[baptiste auguie]

Hi,

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.

HTH,

baptiste

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.
