title: why im getting those signs (look like type) to my header when importing csv table into Dataframe?
body: <p>This is my csv table:</p>
  
  <p><a href="https://i.stack.imgur.com/xf2DH.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/xf2DH.png" alt="enter image description here"></a></p>
  
  <p>were the header are regular</p>
  
  <p>this is the code:</p>
  
  <pre><code>otu &lt;- read.csv("/home/yosdos/Bacteria_Taxonomy.csv",sep="\t",header = T) 
  </code></pre>
  
  <p>and this is the result:</p>
  
  <p><a href="https://i.stack.imgur.com/g8d8Y.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/g8d8Y.png" alt="enter image description here"></a></p>
