title: Read tab delimited text file
body: <p>I am trying to read the data from <strong><a href="https://onlinecourses.science.psu.edu/stat501/sites/onlinecourses.science.psu.edu.stat501/files/data/leukemia_remission.txt" rel="noreferrer">this</a></strong> link in R using the following code but I keep getting warning messages and the dataframe doesn't read the data properly.</p>
  
  <pre><code>url &lt;- 'https://onlinecourses.science.psu.edu/stat501/sites/onlinecourses.science.psu.edu.stat501/files/data/leukemia_remission.txt'
  df &lt;- read.table(url, sep = '\t',header = F, skip = 2,quote='', comment='')
  </code></pre>
  
  <p>Can you tell what I need to change to read the data</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>Adding data snippet</p>
