Hello,

My data doesn't have a unique identifier and I want to generate a unique id of each row of 4 digits (0001, 0002, 0003..... 1114, etc), so I can later merge the ID with other elements such as State Name, (NY0001, NY0002, ... NY1114 etc). I am using _n but only generates a number of length 1.

Thanks,

Tania
