title: R: ggplot2, can I set the plot title to wrap around and shrink the text to fit the plot?
body: <pre><code>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 &lt;- ggplot(data = cars, aes(x = speed, y = dist))
  r + geom_smooth() + #(left) 
  opts(title = my_title)
  </code></pre>
