title: Extract numeric value from ACF in R
body: <p>This is what I am trying to do:</p>
  
  <pre><code>x &lt;- c(1,2,3,3,2,3,4,5,6)
  
  my_acf = acf(x,plot=F)
  
  
  &gt; my_acf
  
  Autocorrelations of series ‘x’, by lag
  
       0      1      2      3      4      5      6      7      8 
   1.000  0.497  0.097 -0.047 -0.050 -0.075 -0.231 -0.376 -0.316 
  </code></pre>
  
  <p>I want to extract only 0.497, the correlation coefficient on the first lag, and I want to have it as a numeric value. How can I do that?</p>
  
  <p>Thank You</p>
