title: Filtering text from numbers and stopwords in R(not for tdm)
body: <p>I have text corpus.</p>
  
  <pre><code>mytextdata = read.csv(path to texts.csv)
  Mystopwords=read.csv(path to mystopwords.txt)
  </code></pre>
  
  <p>How can I filter this text? I must delete:</p>
  
  <pre><code>1) all numbers
  
  2) pass through the stop words
  
  3) remove the brackets
  </code></pre>
  
  <p>I will not work with <code>dtm</code>, I need just clean this textdata from numbers and stopwords</p>
  
  <p>sample data:</p>
  
  <pre><code>112773-Tablet for cleaning the hydraulic system Jura (6 pcs.) 62715
  </code></pre>
  
  <p><code>Jura,the</code> are stopwords.</p>
  
  <p>In an output I expect</p>
  
  <pre><code>  Tablet for cleaning hydraulic system 
  </code></pre>
