title: How to subset from a correlation coefficient dataframe
body: <p>I am a very nubee in R and I am trying to subset from a corr. coefficient dataframe which is</p>
  <p><code>print(CD)</code></p>
  <p>[https://i.stack.imgur.com/kimoa.png]</p>
  <p>and also
  for
  <code>corrplot(CD,method=&quot;number&quot;)</code></p>
  <p>[https://i.stack.imgur.com/rniCw.png]</p>
  <p>So from all these coefficients, I would like to subset coefficients which is over 0.7
  So I have tried a lots of code but it does not work.
  Such as, <code>GG&lt;-subset(CD,cor()&gt;0.7) print(GG)</code></p>
  <p>How could I subset from such case? Thank you.</p>
