Futures prices in quantmod?

Perhaps yahoo's policy prevents from downloading the Dow Jones Industrial
Average, but not less common futures... (getQuote works fine though, so I'm
a bit surprised).

Anyone knows, or knows how to know?

^DJC and ^XAU have historical data, thus you can retrieve their data
with getSymbols.

http://finance.yahoo.com/q/hp?s=^XAU

Most other futures symbols on this page
http://finance.yahoo.com/futures?t=indices
do not have historical data, so you're limited to what you can
retrieve with getQuote.  For example:
http://finance.yahoo.com/q/hp?s=^DJS2

HTH,
Josh
