title: How to select every 5 other observations in R?
body: <p>I have a dataset that contains 10 "houses" with energy production for every minute of the day. Like so:</p>
  
  <pre><code>HouseID Time KwH
  1       1    X
  2       1    X
  3       1    X
  4       1    X
  5       1    X
  6       1    X
  7       1    X
  8       1    X
  9       1    X
  10      1    X
  1       2    X
  2       2    X
  3       2    X
  4       2    X
  5       2    X
  6       2    X
  7       2    X
  8       2    X
  9       2    X
  10      2    X
  </code></pre>
  
  <p>I would like to delete the rows with houseIDs 6 until 10 so that I would be left with only the observations of houseID 1,2,3,4 and 5.</p>
