[R] new error with QuantMod getSymbols

[adolfoyanes at gmail.com]

Thank you very much Joshua. Pardon me  for confusing loadSymbols with getSymbols and not sending the file lista.csv .. Apparently the issue was with Yahoo Finance that day. The next day it worked perfectlty.

Best Regards,

You didn't provide the file "lista.csv", so it's not possible to
reproduce any of these errors.  And there's no call to getSymbols in
your code.  You use loadSymbols, and I am not familiar with that
function.

That said, this sounds like an issue with some of the data being sent
by Yahoo Finance.
