Dear all:

Where can I download the historical daily option closing prices of companies
like Apple computer? Of course for free! I know OptionMetrics provide the
database for charge. But I just need about 10 highly traded companies for
research purpose to verify my model. CBOE seems to provide daily data but it
is inconvenient for me to downolad every day. Is there any better way to do
this in R?
Thanks for your help.
