[R] priceIts and yahoo
Dear R People: About 2 years ago, there were a few messages about the function priceIts from library(its) generating error messages. One of the suggested fixes at that time was to check security software and such. I'm getting the same message tonight, and have checked both from Windows and a Linux installation. The other suggestion was to determine if there is still a problem with the yahoo Finance website. This may still be the problem. Does anyone have any other suggestions, please? Thanks in advance!

I maintain CPAN's Finance::YahooQuote (and am author of two apps, also on CPAN, which use it fairly heavily) and this has been nothing but rock solid in the six years that I've been scraping data from Yahoo, often at a once-a-minute frequency (for the smtm quote display tool). Of note is that Finance::YahooQuote uses a different machine: $QURLbase = "http://quote.yahoo.com/d?f=";; but both chart.yahoo.com and quote.yahoo.com appear to be on the same subnet.

chart.yahoo.com is notoriously fickle (as we have seen from the tseries
example using it). Note that the first command (which gave me no error)
also downloaded from there, so this is not going to be an access issue.
I do get a 404 error on that URL (from two separate ISPs), but not if gdax
is twice replaced by ftse.
I do think the posting guide makes clear this is an issue for the
package maintainer, not for R-help.

Re: [R] priceIts
The error message indicates that a problem is occurring in download.file.
Try to use download.file to download some web page from the internet to
see if that works,
download.file("http://www.google.com";, destfile = "google.htm")
If that does NOT work then examine the download.file help page carefully.
You may need to set your proxy server.
If that did work then as a workaround try using get.hist.quote in package
tseries with the argument retclass = "its". Be sure you have the latest
version of tseries.

Re: [R] priceIts
Well I downloaded the data using the link in your message which suggests that
the code is right. I don't have its loaded (I assume it's from the irregular
time series package) so I can't test the code as you have it.
Have you tried checking to see it it is an issue with the internet (your
browser, blocked sites etc) rather than a problem in R?

It would appear that the URL at Yahoo has changed. If you try your URL in a browser, you get the same 404 msg. Going to the page for securing an IBM quote: http://finance.yahoo.com/q/hp?s=IBM&a=00&b=1&c=1998&d=05&e=30&f=2004&g=d The URL towards the bottom of the page for the CSV download is: http://ichart.yahoo.com/table.csv?s=IBM&a=00&b=1&c=1998&d=05&e=30&f=2004&g=d&ignore=.csv Note the 'ichart' as opposed to 'chart' in your error msg above. A quick review of the R source in the 'its' package suggests that the base URL for Yahoo is hard coded in the priceIts() function and the 'provider' argument is not yet used. I have copied Heywood Giles on this reply as an FYI and for confirmation. A short term workaround would be to edit the function's code using fix(priceIts) and change the base URL in the function body as indicated above. That seems to work for me with a quick check.
