title: Issue when importing dataset: `Error in scan(...): line 1 did not have 145 elements`
body: <p>I'm trying to import my dataset in R using <code>read.table()</code>:</p>
  
  <pre><code>Dataset.df &lt;- read.table("C:\\dataset.txt", header=TRUE)
  </code></pre>
  
  <p>But I get the following error message:</p>
  
  <pre><code>Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings,  :
     line 1 did not have 145 elements
  </code></pre>
  
  <p>What does this mean and how can I fix it?</p>
