title: R gsub not removing '?' in data
body: <p>I have a large df that I am trying to clean up, it goes something like this </p>
  
  <pre><code> Name1. Name2. Var1. Var2....
   name?    ...   ...   ...
   name?    ...   ...   ...
  </code></pre>
  
  <p>So the Names are encrypted and they do include special characters that I do NOT want to remove. </p>
  
  <p>I have been using gsub(), but it does not remove the '?':
  I just want to remove the single '?' at the end of the names that Excel somehow added on. </p>
  
  <p>MyData$Name1 &lt;- gsub("?", "", MyData$Name1)</p>
  
  <p>Nothing seem to have changed and I do not get any error codes.</p>
  
  <pre><code>    Name1. Name2. Var1. Var2....
      name?    x     a     1 ...
      name?    y     b     2 ...
  </code></pre>
  
  <p>Does anyone have any prior experience with something like this? </p>
