Well, yes, according to you second posting I was assuming that your data are already in form of a matrix like so:
{{613, -112}, {1737,
392}, {1685, -176}, {1443, -813}, {891, -39}, {273, 1761}, {356,
2007}, {-8, -198}, {-882, -1634}} // TableForm
(*output: 613 -112
1737 392
1685 -176
1443 -813
891 -39
273 1761
356 2007
-8 -198
-882 -1634*)
Obviously this is not the case in your example ...
