| Dear Rmetrics Core Team,
| I'm trying to import data from yahooFinance with the function yahooSeries from packages fImport. I want to download “Open”, “High”, “Low”, “Close”, “Volume”, and “Adj Close”. But the function yahooSeries don't allow me to download the adjusted series which is in the last column. How can I download this last column named “Adj Close”? I have R version 2.6.1
Wow, R 2.6.1? That is _two years_ old. For software that is free to
upgrade. You should consider upgrading.
Anyway, you could try one of the non-Rmetrics packages:

As you can see, this can adjust OHLC based on the Adj.Close/Close ratio.
