title: Advice on upgrading Emacs (22 -> 24), and also about GUI vs console/terminal
body: <p>I'm using a Macbook Pro (Snow Leopard, 10.6.8) and have been a regular emacs user for the past  few months. I'm trying to install a modified version of Emacs 24.2 <a href="http://vgoulet.act.ulaval.ca/en/emacs/mac/" rel="nofollow noreferrer">provided here</a> to utilize Emacs Speaks Statistics (ESS) from the <a href="http://ess.r-project.org/index.php?Section=download" rel="nofollow noreferrer">downloads page</a>. I currently have 22.1.1:</p>
  
  <pre><code>M-x emacs-version
  GNU Emacs 22.1.1 (mac-apple-darwin) of 2011-06-07 on b1030.apple.com
  </code></pre>
  
  <p>I installed the emacs linked earlier, put it in Applications, and set this in .bashrc:</p>
  
  <pre><code>alias emacs="/Applications/Emacs.app/Contents/MacOS/Emacs -nw"
  </code></pre>
  
  <p>So it seems like it's working correctly as I wrote and successfully ran a short R program. </p>
  
  <pre><code>M-x emacs-version
  GNU Emacs 24.2.1 (x86_64-apple-darwin, NS apple-appkit-1038.36) of 2012-08-27 on bob.porkrind.org
  </code></pre>
  
  <p>Is this the usual way to upgrade to a "newer version" of Emacs? Sorry if this question seems trivial, but I've never done this before (I typically used emacs on a different computer) and the Installation step on the previous website consists of just one sentence. The all-in-one installation method also isn't explained in the official <a href="http://ess.r-project.org/ess.pdf" rel="nofollow noreferrer">documentation</a>.</p>

  <p>A brief side note while I was searching on the web: I believe calling 'emacs file_name' should open a GUI version, while 'emacs -nw file_name' is the console, so I remain using the terminal. But on my Mac, using emacs has the same effect as using emacs -nw. In other words, I can't get a GUI or separate window to show up. Can anyone confirm that <a href="https://superuser.com/questions/278850/open-a-new-window-for-emacs-from-terminal-in-mac">this Super User question has the 'correct' answer</a>? (I don't really have a problem with this, as I hate having another pop-up window, but it would be nice to know for completeness.)</p>
