title: Group time-series observations in R
body: <p><a href="https://i.stack.imgur.com/QeD6u.png" rel="nofollow">Example</a></p>
  
  <p>I have a time seriesAnd I have values from 15 to 15 minutes (so I have 4 values per hour) but I am trying to reduce the data for clustering analysis.</p>
  
  <p>I want to check if I can group per hour in R Software. So I think I need to check for similarities with some kind of statiscal test.</p>
  
  <p>Can someone help me?</p>
