title: How to remove rows from a data frame when the column matches with a different data frame column in R
body: <p>I have a data frame A of the below format
  <code>
  Word     Freq
  p        9531
  can      2085
  /p       2055
  get      1183
  use      1112
  </code></p>
  
  <p>and another data frame B </p>
  
  <p><code>
  Word     Freq
  p        10
  can      2
  /p       55
  </code></p>
  
  <p>Now I want to remove the rows from data frame A that has a matching in the data frame B.
  So my output would be for data frame A</p>
  
  <p><code>
  Word     Freq
  get      1183
  use      1112
  </code></p>
