Not sure what exactly the problem is. Can you give an example? Of course
the first thing would be to make sure that dates are in the same format...
And so far I don't see a good reason to use 'if' - R has extremely
flexible indexing capabilities.

Maybe your stock names in the file were numbers? Maybe you left out the
row.names parameter?

The message means what it says: row names need to be unique. Apparently
yours are not. I.e. You wave multiple rows for the same stock
identifier.
