In words: I want to divide the 3rd column by 100 to keep the length 100 and increasing no of rows needed, where no will be same for all increased rows, but the read will be changed like 2_1,2_2 and...

Hi all, I have a simple question: I have a character vector like this [1] "10_1" "1_1" "11_1" "2_1" "3_1" "4_1" "5_1" "6_1" "7_1" "8_1" [11] "9_1" "1_3" "2_3" "3_3" "4_3" "1_4" "2_4" "3_4" "4_4" "5_4" [21] "6_4&qu...
