Quantmod's function yahooQF()

[jeremystaub28]

Hey guys,

I was wondering if in the function yahooQF() of quantmod package, if it possible to add a date. For example usually one would use the function like this:

getQuote("VOD", what = yahooQF("Dividend Yield"))

all the possible arguments in yahooQF() always give the information for today. My question is how could I get the historical data for these arguments. How could I get the dividend Yield in of stock VOD in 2009 for example? I tried

 getQuote("VOD", what = yahooQF("Dividend Yield"),from='2009-03-01',to='2010-10-01')

but without success... any ideas?  thank you!
