title: getting the name of a dataframe from loading a .rda file in R
body: <p>I am trying to load an .rda file in r which was a saved dataframe. I do not remember the name of it though.</p>
  
  <p>I have tried </p>
  
  <pre><code>a&lt;-load("al.rda")
  </code></pre>
  
  <p>which then does not let me do anything with a. I get the error</p>
  
  <pre><code>Error:object 'a' not found
  </code></pre>
  
  <p>I have also tried to use the = sign.</p>
  
  <p>How do I load this .rda file so I can use it?</p>
  
  <p>I restared R with load("al.rda) and I know get the following error</p>
  
  <pre><code>Error: C stack usage is too close to the limit
  </code></pre>
