title: how to set ticks axes text size using geom_boxplot in ggplot?
body: <p>I´m trying with no success to increase the size of the status label (ticks labels yes/no) on the boxplot below.</p>
  
  <p>What am I doing wrong?</p>
  
  <p>Thanks in advance.</p>
  
  <pre><code>status &lt;- sample(c("yes", "no"), 50, replace=T)
  value &lt;- rnorm(50, mean = 5, sd = 3)
  
  data &lt;- melt(data.frame(status, value),measure.vars="value")
  
  p &lt;- ggplot ( data, aes(x=status, y=value) ) + 
    geom_boxplot(outlier.shape=10, outlier.size=4) + 
    geom_jitter(aes(colour=value), size=3, position = position_jitter(width = .3)) + 
    coord_flip() + 
    scale_colour_gradient(limits=c(min(data$value), max(data$value)),low="#0000FF", high="#FF0000") +
    labs(title="Title",x="status", y="value", colour="value")
  
  p + theme(plot.title = element_text(size = rel(5)), 
                         axis.title.x =element_text(size=10)
  )
  
  p
  </code></pre>
