Removing display of R row names from list.

Is there a way to not include the row names when creating the list? Thanks! I want to do this in display_daily method. I  am able to do it in display_doy method because it is a data frame but fail in the other one which is a list. Thanks for the help!
Here is the link for data frame.http://stackoverflow.com/questions/24428051/removing-display-of-r-row-names-from-data-frame
