title: How to remove axis scale in ggpairs?
body: <p>I have a matrix of scatterplots and correlations depicted below. I would like to get rid of the x and y axis (0, 5, 10, 15) numbers that are at each position in the diagonal.</p>
  
  <p>I would also like to get rid of the word "Corr:", so that only the correlation value appears. </p>
  
  <p>Appreciate your help!</p>
  
  <p>Code:</p>
  
  <pre><code>ggpairs(log2(cpmRos[1:100,] + 1), axisLabels="internal", params=c(size=1), upper=list(params=list(size=5))) 
  + theme(axis.ticks=element_blank(), 
  axis.line=element_blank(), 
  axis.text=element_blank(), 
  panel.grid.major= element_blank())
  </code></pre>
