title: Usage of getSymbols from R package QUANTMOD
body: <p>I would like to use <code>getSymbols</code> to get financial index data from Google finance. When I search for my indices then I get INDEXDB:RXPG for EB.REXX and INDEXDJX:DJUBS for DJ UBS.</p>
  
  <p>A call of the form</p>
  
  <p><code>getSymbols("INDEXDJX:DJUBS",src="google",from = "2007-01-01",to = Sys.Date())</code>
  or
  <code>
  getSymbols("INDEXDB:RXPG",src="google",from = "2007-01-01",to = Sys.Date())
  </code>
  does not work.</p>
  
  <p>Another side question: is there any description of the symbols on google finance?</p>
  
  <p>I don't think that this is necessary for my question but my session info is this:
  R version 2.14.1 (2011-12-22)
  Platform: x86_64-pc-mingw32/x64 (64-bit)
  and I use quantmod 0.4-0.</p>
