getSymbols() quantmod library doubt

Hello Eric,

Thanks for the reply!  Your answer was correct however the my problem was
not explained correctly, my apologies to everyone.
The issue is that once a list is built from the symbols that were download
a mixed type list is formed, see below.

R> class(tickers$VALE3.SA_sd_log)
[1] "numeric"
R> class(tickers$VALE3.SA)
[1] "xts" "zoo"
R> R>

The VALE3 ticker has another list element as well: VALE3.SA_mean_log.
This happens with a few of the symbols only thus the issue at hand seems to
be removing the list "numeric" type elements.

TIA,

Hello,

I'm downloading quote data using the getSymbols() function.  It works

very

well but downloads two additional columns for a few symbols,
namely _mean_log and _sd_log.
Therefore, the traditional 5 column OHLCV data frame has two more columns
in some symbols.

I move all downloaded symbols to a list in order to ease some required
computation.  At the same time, my routine depends on OHLCV data only.
Thus, I need to have a new list discarding the additional columns that
exist in some symbols on the current list.  The symbols with the "extra"
columns must be kept. However their additional columns must be removed.

Could anyone suggest a solution to this problem, please?

Thanks in advance for any help,
