Hi all, I'd like to thank those who helped me with my previous loop function question with agents/events. I have solved the problem with the advice from this community. I have now moved on to the next step, which requires me to find all the transition pair within an event. A sample data and the

Hi all, I'm working on a loop function for a large dataset which contains 1000 different groups. I would like to reconstruct the order of events within each group by using a loop function in R. (Currently the order of events are based on the ascending order of prev_event within the group) A demo
