Subject: Array Processing Multiple Comparisons across columns and rows
Content-Type: text/plain; charset="US-ASCII"
I have an r by c table. I have 5 columns of dates that may or may not be
null. If they are not null they must equal each other across columns and
NOT be equal across observations. I have to be able to identify EACH
Row/Column to set an error flag. Can I do some sort of conditional
array processing across and down?
No. | Date1 | Date2 | Date3 | Date4 | Date5 |
123 |10/24/06| . | . |10/24/06| . |
123 | . |10/25/06| . | . |10/26/06|
123 | . | . |10/27/06| . | . |
