Cbind Error " Object not found"
<p>I am trying to run a panel regression in R studio. When I use cbind command </p>

<pre><code>x&lt;- cbind(DEX, GRW , Debt, Life) 
</code></pre>

<p>for my independent variables,it returns this error; </p>

<blockquote>
  <p>" Error in cbind(DEX, GRW, Debt, Life) : object 'DEX' not found"</p>
</blockquote>

<p>However my dependent variable works fine with cbind</p>

<p>as shown below</p>

<pre><code>y&lt;- cbind(GDP)
</code></pre>

<p>Can you help?
Thanks.</p>
