Subject: Re: How download Yahoo Quote?
Hi Michael:
I tried to simplify the code, but still failed.
con <- url("http://quote.yahoo.com";)
if(!inherits(try(open(con), silent = TRUE), "try-error"))
{
close(con)
x <- get.hist.quote(instrument = "ibm", quote = c("Cl",
"Vol"))
plot(x, main = "International Business Machines Corp")
}
It says:
Warning message:
In open.connection(con) : too many redirects, aborting ...
The more, it doesn't accept " library(quantmod)" and says:
Error in library(quantmod) : there is no package called
'quantmod'
Please help me!
