title: Need to replace characters in a data frame
body: <p>i have a data frame that i need to visualize in R Studio, and for two columns of info (that show the names of points of origin and destination) some of the characters are like this:</p>
  
  <pre><code>St.P&lt;U+00BA&gt;lten
  </code></pre>
  
  <p>This happens for different words like </p>
  
  <pre><code>W&lt;U+00BA&gt;rgl, V&lt;U+00BA&gt;cklabruck
  </code></pre>
  
  <p>this happens only in those two columns of the data frame, </p>
  
  <p>How do i remove those letters, or replace them? i feel like it needs to search those particular strings</p>
  
  <pre><code>&lt;U+00BA&gt;
  </code></pre>
  
  <p>in the two columns and replace them whenever it finds them, do u guys know some code that will help me achieve this?</p>
  
  <p>Thanks!</p>
