title: preventing inherited variable labels in r
body: <p>I have a file of 2,000 columns.  In order to help keep all these variables defined, I'd like to use labels and work package Hmisc.  So far, so good.  My problem: I can't stop any derived variable columns from inheriting the labels.  </p>
  
  <p>I don't want var2 to inherit the label from var1 in the assignment below.  Is there a way to deactivate this basic behavior in R?!  </p>
  
  <pre><code>var1 &lt;- 1:3
  label(var1) &lt;- "var one"
  str(var1)
  
  Classes 'labelled', 'integer'  atomic [1:3] 1 2 3
  ..- attr(*, "label")= chr "var one"
  
  var2 &lt;- var1+10
  str(var2)
  
  Classes 'labelled', 'integer'  atomic [1:3] 11 12 13
  ..- attr(*, "label")= chr "var one"
  </code></pre>
  
  <p>var2 should not be labelled "var one"!!!!</p>
