title: Add variable labels within mutate
body: <p>I am in the process of reworking some old code in order to facilitate learning the <code>tidyverse</code>. In the previous code I would make new variables derrived from present variables, and I would give these new variables a label attribute using <code>label</code> from the <code>Hmisc</code> package. This would look like this.</p>
  
  <pre><code>library(Hmisc)
  
  iris$new &lt;- ifelse(iris$Species == 'setosa', 1, 0)
  label(iris$new) &lt;- "New Variable"
  </code></pre>
  
  <p>which gives this result</p>
  
  <pre><code>&gt; str(iris$new)
   'labelled' num [1:150] 1 1 1 1 1 1 1 1 1 1 ...
   - attr(*, "label")= chr "New Variable"
  </code></pre>

  <p>I was wondering if there is a way to apply this same type of thing within a mutate call.</p>
