Quantmod

I think it is your net-connection problem. It is working fine in my system :
from.dat <- as.Date("01/01/08", format="%m/%d/%y")
to.dat <- as.Date("02/19/09", format="%m/%d/%y")

getSymbols("GE", src="yahoo", from = from.dat, to = to.dat) 
[1] "GE"
Sys.info()
sysname                      release                     
version 
                   "Windows"                      "Vista" "build 6002,
Service Pack 2" 
                    nodename                      machine                       
login 
                      "ARUN"                        "x86"

Hi there,

I have recently installed R 2.9.1 and quantmod 0.3.6

I am trying to get my head around using it, but I keep on getting stopped
at the first hurdle. As an example, I am trying to test the following
code:

from.dat <- as.Date("01/01/08", format="%m/%d/%y") 
to.dat <- as.Date("02/19/09", format="%m/%d/%y") 

getSymbols("GE", src="yahoo", from = from.dat, to = to.dat) 
But I get the following error:

Error in download.file(paste(yahoo.URL, "s=", Symbols.name, "&a=", from.m, 
: 
  cannot open URL
'http://chart.yahoo.com/table.csv?s=GE&a=0&b=01&c=2008&d=1&e=19&f=2009&g=d&q=q&y=0&z=GE&x=.csv'
In addition: Warning message:
In download.file(paste(yahoo.URL, "s=", Symbols.name, "&a=", from.m,  :
  unable to connect to 'chart.yahoo.com' on port 80.

I am not sure where to start to fix this this problem. Has anyone come
accross something like this before?

Thanks,
Eduard

The other issue is that your version is a bit out of date.

The current CRAN version is 0.3-11.  I'll update the website to
reflect this, as well as post a warning that the site has a tendency
to lag behind CRAN or R-forge in terms of most current versions.

Thanks,
Jeff

Thanks Jeff,

I have updated quantmod but am still having connectivity issues. I have
searched through various help files, and I have implemented all the
suggestions.

Do you know of a simple guide to check the connectivity setup of R?

Thanks,
Eduard

See this section of the Windows FAQ:
http://cran.r-project.org/bin/windows/base/old/2.0.0/rw-FAQ.html#The-internet-download-functions-fail_002e

Post to R-help If you still have problems, since this is no longer
finance-related.  You'll likely get faster responses from that list.

Best,
Josh
