I read in ?na.omit that it returns the object with incomplete cases removed. I interpret this to mean that any zoo object row where any column shows 'NA' will be removed from the data set.
That's not what I need, since the 'NA' represents information in my context. However, what I would like to do is eliminate the rows where every column is 'NA'. When I aggregate two factors by date in the zoo object, the rows being with the earliest possible date even if that's not appropriate for the row factor pair. Is there a way to omit only those rows where all columns contain 'NA'?
