title: data.frame tries to assign variable name as tag instead of variable content?
body: <p>I'm trying to assign variable content to a data.frame column name as well as a dataset with the following argument below.</p>
  
  <p>data.frame(tag = value)</p>
  
  <p>But for some reasons it's assigning the variable name as the tag instead of the variable contents?</p>
  
  <pre><code>&gt; dataset_name
  [1] "Dataset_1"
  
  &gt; dataset
    [1]  27.966  55.932  39.346  63.680  82.446
  
  data &lt;- data.frame(dataset_name = dataset)
  
  &gt; data
      dataset_name
  1         27.966
  2         55.932
  3         39.346
  4         63.680
  5         82.446
  </code></pre>
  
  <p>This is the desired output</p>
  
  <pre><code>&gt; data
      Dataset_1
