title: Rserve return type in case of multiple statements
body: <p>Hi i dont quite understand the return type of Rserve in case of multiple command. eg.</p>
  
  <pre><code>a&lt;-rnorm(10);a[4];rnorm(3)
  </code></pre>
  
  <p>it seems Rserve only returns the last evaluated statement,i.e. rnorm(3). Is it possible to get all the three output values with Rserve? </p>
  
  <p>Also i am interested to know how exactly in R can we get the return value of last evaluated expression? Is there a special character in R to get that like in perl?</p>
