library(ggplot2)

my_title = "This is a really long title of a plot that I want to nicely wrap \n and fit onto the plot without having to manually add the backslash n, but at the moment it does not"

r <- ggplot(data = cars, aes(x = speed, y = dist))
r + geom_smooth() + #(left) 
opts(title = my_title)

can I set the plot title to wrap around and shrink the text to fit the plot?
