title: Is there a short cut to typing multiple explanatory variables in lm() in R?
body: <p>I have question regarding the <code>lm()</code> function in R.
  I understand that <code>lm()</code> is used for regression modeling and I know that one can do this:</p>
  
  <pre><code>lm(response ~ explanatory1 + explanatory2 + ... + explanatoryN, data = dataset)
  </code></pre>
  
  <p>Now my question is: "Suppose that <code>N</code> is large, is there a short cut that I can use that doesn't involve me having to write all <code>N</code> variable names?"</p>
  
  <p>Thanks in advance!</p>
  
  <p>Edit: I left out a big part of the question that I really needed an answer to. Suppose that I wanted to remove <code>1</code> to <code>k</code> explanatory variables and only include <code>n-k</code> of those variables.</p>
