Examples

p <- qplot(mpg, wt, data = mtcars)
p + expand_limits(x = 0)
p + expand_limits(y = c(1, 9))
p + expand_limits(x = 0, y = 0)

qplot(mpg, wt, data = mtcars, colour = cyl) + 
expand_limits(colour = seq(2, 10, by = 2))
qplot(mpg, wt, data = mtcars, colour = factor(cyl)) + 
expand_limits(colour = factor(seq(2, 10, by = 2)))
