title: Getting Stargazer Column labels to print on two or three lines?
body: <p>I have some models that have long titles to be fully explanatory. It would be helpful to have them print their descriptors or titles on two lines. This reads the line break character, but the resulting latex output doesn't recognize it.     </p>
  
  <pre><code>var1&lt;-rnorm(100)
  var2&lt;-rnorm(100)
  df&lt;-data.frame(var1, var2)
  mod&lt;-lm(var1~var2)
  library(stargazer)
  stargazer(mod, column.labels='my models\nneed long titles')
  </code></pre>
  
  <p>Thanks.</p>
