Re: [R] Extract Data from Yahoo Finance
Vikram,
Â
Thanks for this.
Â
The field names we put like this:
quote = c("Open", "High", "Low", "Close")
Â
But in order to download all the fields, what are the names I need to use in
the object quote.Â
In Yahho Finance these are special tags.
Â
The special tags are:
a=Ask, b= Bid, ..., v= Volume, W= 52-week Range, x= Stock EXchange
Â
quote= c("Open", "High", "Low", "Close", "Ask", "Bid", , "W", "x"). What
are the names I can use to download Ask, Bid, ..., Stock Exchange?
Â
Once again, thank you very much for the time you have given.
Â
Regards,
Â
Deb
