[R] ipf function in R

[Chandra Shah]

Hi
I have a 3 x 2 contingency table:
10 20
30 40
50 60
I want to update the frequencies to new marginal totals:
100 130
40 80 110
I want to use  the ipf (iterative proportional fitting) function which 
is apparently in the cat package.
Can somebody please advice me how to input this data and invoke ipf in R 
to obtain an updated contingency table?
Thanks.
By the way I am quite new to R.
