Controlling ggplot2 legend display order

by

In 0.9.1, the rule for determining the order of the legends is secret and unpredictable.
Now, in 0.9.2, dev version in github, you can use the parameter for setting the order of legend.

Here is the example:

plot <- ggplot(diamond.data, aes(carat, price, colour = clarity, shape = cut)) +
  geom_point() + opts(legend.position = "top")

plot + guides(colour = guide_legend(order = 1), 
              shape = guide_legend(order = 2))

enter image description here

plot + guides(colour = guide_legend(order = 2), 
              shape = guide_legend(order = 1))

enter image description here
