title: R- plot numbers instead of points
body: <p>I have successfully made a scatterplot, with different symbols for each data series.  But what I want to do is make the same scatterplot with the point to show up as numbers.  Not the value of each point, just an assigned number.  </p>
  
  <p>As of right now, I have three depths I am plotting (0, 3, 6cm).  I have all my 0cm as triangles, etc.  I want my 0cm points to be the character 0, the 3cm points to show up as 3, and the 6cm points to show up as 6.  </p>
  
  <p>Is this possible?</p>
