title: Manually changing linetype order and offsetting error bars in ggplot
body: <p>Using these data   </p>
  
  <pre><code>Data &lt;- structure(list(value = c(180, 528, 180, 147, 468, 151, 194, 568, 
  210), SE = c(21.7869586486209, 21.0831764730322, 21.2726560659361, 
  21.7869586486209, 21.0831764730322, 21.2726560659361, 21.7869586486209, 
  21.0831764730322, 21.2726560659361), PredictionType = c("InSitu", 
  "ExSitu", "ExSitu", "ExSitu", "InSitu", "ExSitu", "ExSitu", "ExSitu", 
  "InSitu"), Area = c("AAA", "BBB", "CCC", "AAA", "BBB", "CCC", 
  "AAA", "BBB", "CCC")), .Names = c("value", "SE", "PredictionType", 
  "Area"), class = "data.frame", row.names = c(NA, -9L))
  </code></pre>
  
  <p>and the following code I can produce the plot below.</p>
  
  <pre><code>ggplot(Data)+
    geom_point(aes(x=Area, y=value, color=Area),size=3, shape=1)+
    geom_errorbar(aes(x=Area, ymin=value-SE, ymax=value+SE, color=Area, linetype = PredictionType),cex=0.75)
  </code></pre>

  <p>The linetype is correctly distinguishing between ExSitu and InSitu predictions, but I want the line type to be reversed.  Equivocally, i want the dotted line to be ExSitu and the solid line to be InSitu.</p>
  
  <p>Also, is it possible to offset the error bars so that they are not directly on top of each other?  Ideally I would want the solid InSitu estimate centered over the area (AAA, BBB, CCC) and the two dotted ExSitu estimates slightly right and left of center.</p>
  
  <p>Thanks in advance.  </p>
