title: Remove seconds from time in R
body: <p>I am trying to remove the seconds from a column of hours in POSIXct format:</p>
  
  <pre><code>#"2016-04-02 10:33:45 COT" "2016-04-02 22:19:24 COT"
  #"2016-04-09 17:47:13 COT" "2016-04-13 16:56:23 COT"
  
  x &lt;- structure(c(1459589625, 1459631964, 1460220433, 1460562983),
       class = c("POSIXct", "POSIXt"), tzone = "")
  </code></pre>
  
  <p>I am trying this but I am not seeing results:</p>
  
  <pre><code>y &lt;- as.POSIXct(x, format = "%d/%m/%Y %H:%M")
  </code></pre>
