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

[Jeff Ryan]

R_help Help:

While I know this has been answered, I'll just make a few comments
w.r.t. getting the most out of R-finance.

You should really use your real name.  We are all actual people, who
spend actual time on writing, documenting, and supporting our code.  I
realize it isn't a universal standard, but real names are generally
appreciated.

The help files [very well written, mind you ;-) ], are the first place
to always start.  From there a look at the args() or source is
helpful. Following that a search of previous posts is a good next
step.  After all that fails, posting an well written question with a
self-contained example is really the only way to ask for help.

?getSymbols
example(getSymbols)
args(getSymbols.yahoo)

There is also a reasonable amount of code/examples on http://www.quantmod.com


All would have pointed out that the function recognizes 'start' as
much as it does 'nonsense_madeup_arg'.

In general using the list isn't a 'do my homework', but rather a 'I've
done my homework, and I still can't figure it out' tool.
