body: <p>I have many R sessions open. Searched in Rgui Options, not sure how to name each of the sessions that are open and in use. </p>

  <p>Searched in GUI Preferences in R, couldn't get any help. Checked on how to do it with commands, it says each session has its own process ID, to find that used <code>Sys.getpid()</code></p>
  
  <p>Want to select R session based on name of the R session window. </p>
