R devel - Jun 2003 - get.hist.quote not connecting to yahoo (PR#3188)

Full_Name: Alexander Gracian
Version: 1.7
OS: windows XP
Submission from: (NULL) (217.158.140.82)



Since yesterday morning get.hist.quote in tseries has not been connecting to
yahoo 90% of the time. Is this a problem or change at Yahoo's end?

Example of R output...

Tring to pulling in 30 days of pricestrying URL

unable to connect to 'chart.yahoo.com' on port 80.
Error in download.file(url, destfile, method = method) :

This is clearly stated to be a connection problem. If it ever works it is
not an R problem, and that is the case (as you say and we find).

Please don't abuse R-bugs, which is for bugs in R, not bugs in your
internet connectivity nor even for bugs in contributed packages such as
tseries.

It `works' here, but there seems to be a problem in tseries:
>      x <- get.hist.quote(instrument = "^spc", start =
"1998-01-01",
+                          quote = "Close")
trying URL 
`http://chart.yahoo.com/table.csv?s=^spc&a=0&b=01&c=1998&d=5&e=03&f=2003&g=d&q=q&y=0&z=^spc&x=.csv'
Content type `application/octet-stream' length unknown
opened URL
downloaded 65Kb

time series starts 1998-01-02
Error in Ops.difftime((end - start) * frequency, 1.01) : 
        both arguments of + must be difftime objects

because get.hist.quote passes classed objects as start and end to ts().

You have a spelling problem and a new-line problem in your code!
