[R] Automatic Recoding

[Thomas Chesney]

I have a text file full of numbers (it's a edgelist for a graph) and I would like to recode the numbers as they are way too big to work with. So for instance the following:

676529098667    1000198767829
676529098667    100867672856227
676529098667    91098726278
676529098667    98928373
1092837363526   716172829

would become:

0   1
0   2
0   3
0   4
5   6

i.e. all 676529098667 would become 0, all 1000198767829 would become 1 etc.

If I read all the values into a matrix, is there a pre-existing function that can do the recoding?

Thank you!
