Like Eric, I cannot reproduce your result. In addition
to Dirk's suggestions for debugging:
i) start from a clean session (no workspace-loading);
ii) since your column 'tickers$BBAS3.SA_log_returns' is named
"daily.returns" -- any chance you are (accidentally) calling
'quantmod::dailyReturn' in your code?
