title: Use strsplit with multiple delimiters
body: <p>How can I split this</p>
  
  <pre><code> Chr3:153922357-153944632(-)
   Chr11:70010183-70015411(-)   
  </code></pre>
  
  <p>in to </p>
  
  <pre><code>    Chr3  153922357 153944632 - 
      Chr11 70010183  70015411  -   
  </code></pre>
  
  <p>I tried <code>strsplit(df$V1,"[[:punct:]]"))</code>, but the negative sign is not coming in the final result</p>
