[R-SIG-Finance] Newbie quantmod periodicity question

[Brian G. Peterson]

Everything I said below is correct, however, I suspect that you may not 
have considered that there is no way to go from daily data to hourly 
data....

You'll need to get higher-frequency data, see other posts on this list 
about using getQuote to get higher frequency data from Yahoo.
