title: split string by multiple characters
body: <p>I would like to split a character by multiple delimiters defined in a vector: </p>
  
  <pre><code>text1   &lt;- "aweoiutw839572/)(&amp;2aslk2468" 
  text2   &lt;- "147we547iu5erhg24tzu" 
  dat &lt;-  rbind(text1, text2)
  vector &lt;- c("we", "iu", "24")
  </code></pre>
  
  <p>The result should be: </p>
  
  <pre><code>var1 del1 var2 del2  var3                del3 var4
  a    we   o    iu    tw839572/)(&amp;2aslk   24   68
  147  we   547  iu    5erhg               24   tzu
  </code></pre>
  
  <p>Any ideas with <code>strsplit</code> ? </p>
