title: Is there a way to parallelize tidyr?
body: <p>I am using Tidyr to complete a time series for balances and transactions, however due to the number of individuals computation is taking a significant amount of time. I have 16 cores and R is only using one is there any way to parallelize Tidyr?  </p>
  
  <p>What I have is simply this (it is proceed by a group by such that the time series for each individual is completed respectively) </p>
  
  <pre><code>%&gt;%tidyr::complete(Date = seq.Date(min(Date), max(Date), by="day"))%&gt;%
  </code></pre>
