title: ggplot polar plots text is cut off
body: <p>I'm attempting to find a way to remove the text that gets cut off from the edges on a polar plot using ggplot (see attachment).  I've tried manipulations in theme, text and geom_text using vjust,hjust,nudge_y...etc. and I cannot make them move at all. </p>
  
  <pre><code>ggplot(ds, aes(factor(TraitIds), UserDat, fill = factor(TraitIds))) + 
    geom_bar(width = 1,stat="identity") + 
    scale_y_continuous(breaks = 0:1) + 
    coord_polar() +
    geom_text_repel(nudge_y=0.3)+
    labs(x = "Raw Trait Scores", y = "") +
    theme( panel.background = element_rect(fill = "white",
                                          colour = "white",
                                          size = 0.5, linetype = "solid"),
          panel.grid.major = element_line(size = 0.1, linetype = 'solid',
                                          colour = "black"), 
          panel.grid.minor = element_line(size = 0.1, linetype = 'solid',
                                          colour = "black"),
          legend.position = "none",
          axis.text.y = element_blank(),
          text = element_text( face = "plain",
                              colour = "black", size = 10,
                              hjust = 100, vjust = 1000, angle = 0,
                              lineheight = 0.9),
          axis.ticks = element_blank())
  </code></pre>
