Subject: How to use tapply with more than one variables grouped
In-Reply-To: <6E8D8DFDE5FA5D4ABCB8508389D1BF88D5BB06@SRVEXCHMBX.precheza.cz>
To take this example I reduced the number of records absurdly. In the
original database there are 48 000 candidates and dozens of states. There is
no way to analyze data visually. I would not put 400 mb of tables here. But
based on the example how could list the states where obama received more
contribution?
