title: How to plot correlation matrix in R with already derived correlation values between variables?
body: <p>I have an output table which looks like:</p>
  
  <pre><code>Vars Corr  SE
  1_2  0.51  0.003
  1_3  0.32  0.001
  ...
  49_50 0.23 0.006
  </code></pre>
  
  <p>where correlation values were derived in another software for variables stated in <code>Vars</code> (1_2 refers to between Variable 1 and 2). What is the best way to convert this into a format which could display the correlation matrix between all 50 variables?</p>
  
  <p>I'm assuming there needs to be a way to make the diagonals 1 as well?</p>
  
  <p>Thanks!</p>
