title: Split an address separated by comma
body: <p>I have a data.frame of house sale transactions. At the moment the Address is in format. </p>
  
  <pre><code>  1 Accacia Avenue,This Town,This City,A10 1AA.
  </code></pre>
  
  <p>Is there a way I can split this into different columns in the data.frame removing the <code>,</code> at the same time?</p>
  
  <p>I have created a separate vector for now just containing addresses.</p>
  
  <p>The Address in stored in the Address column of the Dataframe - <code>data</code>.</p>
  
  <pre><code>head(data$Address)
  [1] 22 Amesbury Road, Feltham (TW13 5HJ)
  [2]Flat 11, Gloucester Court, Links Road, London (W3 0EW)
  </code></pre>
  
  <p>I need to split this into </p>
  
  <pre><code>"Address1", "Address2", "Address3"
  </code></pre>
  
  <p>and I also need to remove the postcode within <code>()</code> as I already have this in a separate field.</p>
