title: Get full properties of R object
body: <p>There is a function I have used before to get the full properties of an object in R (I used it before to find out why two dataframes which looked identical failed the checkEquals RUnit check).</p>
  
  <p>The structure (<code>str()</code>) and attributes (<code>attributes()</code>) look identical. Can anyone point me in the right direction as to what the function which shows the full properties of an object is please?</p>
