Hi Michael:
I installed: install. packages("quantmod") and now it accept
library(quantmod) sentence. BUT after input:
* 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")
}*
The result is the same:
* Warning message:
In open.connection(con) : too many redirects, aborting
...*
ps: the 1st line of my code is:
library(quantmod)
