Problem with allp ossible combination.
Dear R Users,
Suppose I have a dataset like this:
a b
39700 485.00
39300 485.00
39100 480.00
38800 487.00
38800 492.00
39300 507.00
39500 493.00
39400 494.00
39500 494.00
39100 494.00
39200 490.00
Now I want get a-b for all possible combinations of a and b. Using two 'for'
loop it is easy to calculate. But problem arises when row length of the data
set is large eg. 1000 or more. Then R takes lot of time to do that. Can
anyone please tell me whether there is any R-function to do such kind of job
quickly?
Thanks and re...

I'm not aware of any zaptel driver for such HFC USB modem (some Xorcom's
products use USB, so ...) so I'm inclined to think it's not possible but
it's better to ask ...
Cheers
