getFinancials (quantmod) and tq_get (tidy quant) not working?

问题

I'm getting the same error in both quantmod and tinyquant for financials data. Can anyone see if this is reproducable? Is this a google finance server issue? None of the below functions have been working for me.I'm not sure if it's me or the server.

    tq_get("AAPL", get= "financials")
    [1] NA
    Warning message:
    x = 'AAPL', get = 'financials': Error in thead[x]:thead[x + 1]: NA/NaN 
    argument

and:

    getFin("AAPL")
    Error in thead[x]:thead[x + 1] : NA/NaN argument

Can somebody help?

回答1:

Yes I get the same issue for the past couple of days as well. I think it may have to do with a change on the part of Google Finance. The site is now different and url as well.

Hi @Joe I faced the same problem, because google change its page, so I wrote a function to get data from Yahoo Finance. Its output is similar to getFin. I hope it can help you.

You can call it as scrapy_stocks(c("AAPL","GOOGL")) and access its data as AAPL.f$IS,AAPL.f$BS or AAPL.f$CF.
