title: R: Hide control variables from lm display
body: <p>I would like to do a linear regression with <code>y</code> being my dependent variable and <code>x1 x2 x3</code> being my independent variables. I also have "control" variables <code>z1 z2 z3</code> which I would like to include but not display the results of.</p>
  
  <pre><code>summary(lm(y~x1+x2+x3+z1+z2+z3))
  </code></pre>
  
  <p>Is there a way for summary not to display the coefficients for my control variables?</p>
