title: Process analyses using bupaR
body: <p>I am basically looking at three types of analyses on the patients data which comes along with installing the bupaR package:</p>
  
  <ol>
  <li>Plot for throughput time along with filters.</li>
  <li>Plot for case frequency along with filters.</li>
  <li>Plot for activity frequency along with filters.</li>
  </ol>
  
  <p>I tried this code for throughput time from the website bupar.net:</p>
  
  <pre><code>library(bupaR)
  library(edeaR)
  library(eventdataR)
  library(processmapR)
  library(processmonitR)
  library(xesreadR)
  library(lubridate)
  library(dplyr)
  
  patients %&gt;% throughput_time("log") %&gt;%plot() 
  </code></pre>
  
  <p>but it is throwing an error. Please help, thanks.</p>
