Question

If I use \n with labs(title="whatever \n comes after this") I end up with quite a big space between the lines. Is there a way to influence it? (I mean except font-size of the title itself).

Answer 1

you can do something like this ( option lineheight to modify line spacing)

  p <- qplot(mpg, wt, data = mtcars)
  p <- p + ggtitle("whatever \n comes after this") + 
  theme(plot.title = element_text(lineheight=.1))
  p
