regular expressions slay me
I am furiously trying to find what I am looking for in Pickaxe book and
not finding it.
I''m getting some values back from a posted form and I need to get the
''id'' number off the backend. The ''String'' will always come back to me
as...
Some_name\r\n123
where 123 is actually the id number which I need to execute the find.

Still can't find missing data
I'm trying to prepare some cross tabs, looking at a number of variables against a variable "connector" which has 2 values: "OD Passenger" and " Connector".
When I produce a xtabs one way I have observations under "Connector" but against a different variable "Connector" shows all 0 values.
