title: How to display two digit number as points on plot in R?
body: <p>I am trying to make a scatter plot which uses numbers for each point on the graph, rather than black dots. I can do this for numbers 9 and under, but anything 10 and above is represented by 1 on the resulting plot. The numbers represent individual subjects, and I have 13 of them, with a number of data points from each individual.</p>
  
  <p>I am using the <code>plot</code> function for this as I have worked out how to do all the other things I need with that so I am reluctant to change to another plot type/command.</p>
  
  <p>Sample code:</p>
  
  <p><code>plot(dif ~ mean, pch=as.character(Subject.Number), data = Cov5.1)</code></p>
  
  <p>But <code>pch=as.character</code> only works for single digit numbers.
  I have seen solutions on here that talk about using text or labels but for whatever I cannot get either of those to work. </p>
  
  <p>Here is one previous question, but the answer doesn't work for me:

  <p>How can I create a scatter plot which uses numbers instead of dots? </p>
