I have a long table of let's say 198 variables. I would like to insert an ID column where R counts for me from 1-22 chronologically, repeating each count 9 times. (198/22=9)

In other words I want the sequence to go : 1 (9 times), 2 (9 times), 3(9 times) until it reaches 22 (9 times). I have already tried different ways but have not been able to figure it out. Thank you so much in advance.

We can use rep

rep(1:22, each = 9)
