Dear all,
I need to remove any rows AFTER the label becomes 1. For example, for ID
1, the two rows with TIME of 15 & 18 should be removed; for ID 2, any rows
after time 6, i.e., rows of time 9-18, should be removed. Any
suggestions? Thank you very much!
The current dataset looks like the following:
ID TIME LABEL
1 0 0
1 3 0
1 6 0
1 9 0
1 12 1
1 15 0
1 18 0
2 0 0
2 3 0
2 6 1
2 9 0
2 12 0
2 15 0
2 18 0
Thanks a lot!
Jennifer
