title: Remove Column Names in R
body: <p>I am relatively new to R and am struggling to remove the column names for this graph. Here is a small sample of the 4417 row data which contains 3 trials and 8 tests. I have used row.names=FALSE, which doesn't remove their names from the graph.</p>
  
  <pre><code>Test    TestNumber  Display Trial   TrueValue   Subject Response
  Vertical Distance, Aligned  1   1   B   0.6 1   0.6
  Vertical Distance, Aligned  1   1   B   0.6 2   0.55
  Vertical Distance, Aligned  1   1   B   0.6 3   0.7
  Vertical Distance, Aligned  1   1   B   0.6 4   0.6
  Vertical Distance, Aligned  1   1   B   0.6 5   0.65
  Vertical Distance, Aligned  1   1   B   0.6 6   0.6
  Vertical Distance, Aligned  1   1   B   0.6 7   0.5
  Vertical Distance, Aligned  1   1   B   0.6 8   0.65
  Vertical Distance, Aligned  1   1   B   0.6 9   0.5
  
  
  ggplot(ds, aes(x=factor(Response),
  y=TrueValue, 
  row.names=FALSE, 
  color=Trial,sd(x))) 
  + geom_boxplot(notch=FALSE) 
  + scale_y_continuous("Response") 
  + scale_x_discrete('Trial') 
  + theme_bw() 
  + theme(axis.text.x=element_text(angle = -90, hjust = 0)) 
  + theme(text=element_text(size=10, family="Arial")) 
  + ggtitle('Trial Median Comparison \n to Look for Over Estimation')
