## Not run:
# faceting displays subsets of the data in different panels
p <- ggplot(diamonds, aes(x=carat, y=..density..)) + geom_histogram(binwidth=0.2)
# With one variable
p + facet_grid(. ~ cut)
p + facet_grid(cut ~ .)
# With two variables
p + facet_grid(clarity ~ cut)
p + facet_grid(cut ~ clarity)
p + facet_grid(cut ~ clarity, margins=TRUE)
# You can also use strings, which makes it a little easier
# when writing functions that generate faceting specifications
# p + facet_grid("cut ~ .")
