[R-SIG-Finance] Earliest available data on yahoo to download

[R_help Help]

Hi - I used xts and zoo to try to download stock data from yahoo. I
set the start date to 2005-01-01. I got only portion starting from
2007-01-03. However, if I got to yahoo and manually click to download
historical data it will give me everything. So is this a known problem
with xts and zoo? Or is it a problem with yahoo? Is there anyway
around? Thank you in advance.
