p + labs(x = "New x label")
p + xlab("New x label")
p + ylab("New y label")
p + ggtitle("New plot title")

# This should work independently of other functions that modify the
# the scale names
p + ylab("New y label") + ylim(2, 4)
p + ylim(2, 4) + ylab("New y label")

p <- ggplot(mtcars, aes(mpg, wt, colour = cyl)) + geom_point()
p + labs(colour = "Cylinders")

# Can also pass in a list, if that is more convenient
p + labs(list(title = "Title", x = "X", y = "Y"))
