title: Clustered Barplots: Problems with labels
body: <p>I have a dataset that looks like that, I want to plot the exact same bar plot in R. </p>

  <p>This is what I've been trying:</p>
  
  <pre><code>barplot(as.matrix(table[,2:8]), beside = T, ylim= c(0,1),
          col = c("red", "blue", "green", "yellow", 
                  "orange", "purple", "cyan", "grey", 
                  "deeppink", "red4", "black", "brown"))
  </code></pre>
  
  <p>I get a bar plot, but now when I want to change the labels instead of a,b,c...g to this:</p>
  
  <pre><code>(-0.20,-0.15) 
  (-0.15,-0.10)
  .
  .
  .
  (0.20,0.25)
  </code></pre>
  
  <p>I get an X character in front of every label I was trying to write:</p>
