I use the excellent quantmod to load stock prices from yahoo. This has never caused me any problems. However ever since yesterday I can not download any more stock quotes.

I also tried the get.hist.quote function from the tseries package but this gives me about the same error.

Below is the code that I tried:

library('quantmod','PerformanceAnalytics')   
tickers = '^GSPC'

data <- new.env()
getSymbols(tickers, src = 'yahoo', from = '1970-01-01', env = data, auto.assign = T)

This gave 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=^GSPC&a=0&b=01&c=1970&d=0&e=02&f=2014&g=d&q=q&y=0&z=^GSPC&x=.csv' In addition: Warning message: In download.file(paste(yahoo.URL, "s=", Symbols.name, "&a=", from.m, : InternetOpenUrl failed: 'A connection with the server could not be established'

As far as I can see the link to yahoo finance doesn't work anymore (I also tried copy pasting the link to chrome but there I can't open it either).

Does anyone know what happend? Did yahoo finance change or am I missing an update from quantmod or something?

Thanks in advance for any help!

    Had you searched, or just looked at the quantmod-tagged questions, you would have saved yourself some time. – Joshua Ulrich Jan 02 '14 at 18:11
  • Since this seems to be time-dependent, I re-ran both answers to [this question](http://stackoverflow.com/questions/20850143/quantmod-getsymbols-error-trying-to-replicate-answer) today (2014-01-02). Google worked, Yahoo did not. – jlhoward Jan 02 '14 at 18:20

    @jlhoward: it's not time-dependent, your solution is simply wrong. ;) My patch on R-Forge still works. – Joshua Ulrich Jan 02 '14 at 18:46
  • @JoshuaUlrich - Provide a link to the patch please. – jlhoward Jan 02 '14 at 19:07
