getSymbols does not retrieve Yahoo financial data

[ghost]

Yahoo may implement some changes on its financial data and the

f = getSymbols('SPY', src = 'yahoo', auto.assign = FALSE)

does not retrieve any data. This only happens since yesterday.

Would you please review whether the getSymbols() needs update too? The python added a decryption function in the pandas_datareader/yahoo/daily.py to make it work again. See https://github.com/pydata/pandas-datareader/issues/952.

Any help is greatly appreciated. Thank you very much.

Thanks for the report. Can you please provide the output of sessionInfo()?

This is a timeout issue, which is likely caused by the user's internet connection and/or an issue with the Yahoo Finance servers. Either way, I can't fix it via changes in quantmod, so I'm closing.
