title: ggplot2: plotting bars when using stat_summary()
body: <p>Here is my current script and the output:</p>
  
  <pre><code>ggplot(data.and.factors.prov,aes(x=assumptions,y=FP,
                         colour=factor(Design.Complexity))) +
         stat_summary(fun.data=mean_cl_normal,position=position_dodge(width=0.5)) +
         geom_blank() + scale_colour_manual(values=1:7,name='Design Complexity') + 
         coord_flip()
  </code></pre>

  <p><strong>How can I have (horizontal) bars (starting at FP=0 and ending at the point position) instead of points ?</strong> (I don't want to lose the error bars)</p>
  
  <p>I'd like to give you my data.and.factors.prov data.table but it is too big to be posted ! If you need a reproducible example, please let me know how I can give you my data set ?!</p>
